Exhibit 99.4

Management's Discussion and Analysis of Financial Condition and Results of Operations for the Six Months Ended June 30, 2016

        Revenue composition and sources of revenue growth.    In the first six months of 2016, we generated total revenues of RMB8.9 billion (US$1.3 billion).

        We generate our revenues primarily from the accommodation reservation and transportation ticketing businesses. The table below sets forth the revenues from our principal lines of business for the periods indicated, both in absolute amounts and as percentages of our total revenues.

(1)
Accommodation reservation revenues mainly represent revenues from reservations of hotels, hostels, vacation rentals and other accommodation-related services.

(2)
Transportation ticketing services revenues mainly represent revenues from reservations of air tickets, railway tickets and other transportation related services.

(3)
Translation from RMB amounts into U.S. dollars was made at a rate of RMB6.4778 to US$1.00 as of December 31, 2015. See "Exchange Rate Information."

(4)
Translation from RMB amounts into U.S. dollars was made at a rate of RMB6.6459 to US$1.00 as of June 30, 2016. See "Exchange Rate Information."

        We present a majority of our revenues on a net basis. Revenues are recognized at gross amounts received from customers in cases where we undertake the majority of the business risks and acts as principal related to the services provided. The amount of revenues recognized at gross basis was immaterial during the six-month periods ended June 30, 2015 and 2016, respectively.

        PRC laws and regulations impose substantial restrictions on foreign ownership of air-ticketing, travel agency, advertising and value-added telecommunications businesses in China. Therefore, we conduct part of our transportation ticketing and packaged-tour businesses through our consolidated affiliated Chinese entities. Historically, we generated a portion of our revenues from fees we charge these entities.

        Accommodation reservation.    Revenues from our accommodation reservation business have been our primary source of revenues since our inception. Revenues from our accommodation reservation business have increased from RMB2.1 billion in the first six months of 2015 to RMB3.4 billion (US$510 million) in the first six months of 2016, representing 40% and 38% of our total revenues in the respective periods.

        We generate our accommodation reservation revenues primarily through commissions from hotels. We recognize revenues when we receive confirmation from a hotel that a customer who booked the hotel through us has completed the stay at the applicable hotel and upon confirmation of the commissions amount by the hotel. While we generally agree in advance on fixed commissions with a particular hotel, we also enter into a commission arrangement with many of our hotel suppliers that we refer to as the "ratchet system." Under the ratchet system, our commission per room night for a given

1


hotel increases for the month if we sell in excess of a pre-agreed number of room nights with such hotel within the month.

        Transportation ticketing.    Transportation ticketing revenues mainly represent revenues from reservations of air tickets, railway tickets and other related services. Revenues from our transportation ticketing business have increased from RMB2 billion in the first six months of 2015 to RMB4 billion (US$595 million) in the first six months of 2016, representing 39% and 44% of our total revenues in the respective periods.

        We conduct our transportation ticketing business through our consolidated affiliated Chinese entities, as well as a network of independent transportation ticketing service companies. Commissions from transportation ticketing services rendered are recognized after transportation tickets are issued.

        Packaged-tour.    Revenues from our packaged-tour business have increased from RMB725 million in the first six months of 2015 to RMB1 billion (US$155 million) in the first six months of 2016, representing 14% and 12% of our total revenues in the respective periods.

        Commissions from packaged-tour services rendered are recognized after the packaged-tour services are rendered and collections are reasonably assured. We conduct our packaged-tour business mainly through our consolidated affiliated Chinese entities, which bundle the packaged-tour products and receive referral fees from different travel suppliers for different components and services of the packaged tours sold through our transaction and service platform. Referral fees are recognized as revenues after the packaged-tour services are rendered.

        Corporate travel.    Corporate travel revenues primarily include commissions from transportation ticket booking, accommodation reservation and packaged-tour services rendered to corporate clients. Revenues from our corporate travel services have increased from RMB213 million in the first six months of 2015 to RMB263 million (US$40 million) in the first six months of 2016, representing 4% and 3% of our total revenues in the respective periods.

        Other products and services.    Other products and services primarily consist of online advertising services, the sale of Property Management System ("PMS") and related maintenance service. We place our customers' advertisements on our apps and websites. We conduct the advertising business through Ctrip Commerce, and we recognize revenues when Ctrip Commerce renders advertising services. We conduct PMS sale and maintenance business through JointWisdom, one of our subsidiaries. The sale of PMS is recognized upon customer's acceptance. Maintenance service revenue is recognized ratably over the term of the maintenance contract on a straight-line basis.

        Cost of revenues are costs directly attributable to rendering our revenues, which consist primarily of payroll compensation of customer service center personnel, payments to travel suppliers, credit card service fee, telecommunication expenses, and other direct expenses incurred in connection with our transaction and service platform.

        Cost of revenues accounted for 30% and 28% of our net revenues for the six-month period ended June 30, 2015 and the six-month period ended June 30, 2016, respectively. We believe our relatively low ratio of cost of revenues to revenues is primarily due to high efficiency of our customer service system. Our cost efficiency was further enhanced by our mobile operations, which require significantly fewer service staff to operate and maintain. The decrease of percentage of cost of revenues over net revenues was largely due to enhanced efficiency of our customer service.

2


        Operating expenses consist primarily of product development expenses, sales and marketing expenses, and general and administrative expenses, all of which include share-based compensation expense. In the first six months of 2015 and 2016, we recorded RMB312 million and RMB2.4 billion (US$363 million) of share-based compensation expense, respectively. The increase is primarily due to the share incentives granted in 2016 as well as the consolidation of Qunar's financial results since December 31, 2015. Share-based compensation expense is included in the same income statement category as the cash compensation paid to the recipient of the share-based award.

        Product development expenses primarily include expenses we incur to develop our travel suppliers network and expenses we incur to maintain, monitor and upgrade our transaction and service platform. Product development expenses accounted for 33% and 48% of our net revenues in the first six months of 2015 and 2016, respectively. This increase was primarily due to an increase in share-based compensation charges as a result of the share incentives granted in 2016 and our consolidation of Qunar's financial results since December 31, 2015. In the first six months of 2016, we continued to increase our spending on product development to increase operational efficiency in order to capture business opportunities in new products and services as well as in new markets.

        Sales and marketing expenses primarily comprise of payroll compensation and benefits attributable to our sales and marketing personnel, advertising expenses, and other related marketing and promotion related expenses. Our sales and marketing expenses accounted for 29% and 34% of our net revenues in the first six months of 2015 and 2016, respectively. The increase of sales and marketing expenses as a percentage of net revenues in the first six months of 2016 was primarily due to an increase in share-based compensation charges as a result of the share incentive awards granted in 2016.

        General and administrative expenses consist primarily of payroll compensation, benefits and travel expenses attributable to our administrative staff, professional service fees, as well as administrative office expenses. Our general and administrative expenses accounted for 11% and 17% of our net revenues in the first six months of 2015 and 2016, respectively. The increase of general and administrative expenses as a percentage of net revenues in the first six months of 2016 was primarily due to an increase in share-based compensation charges as a result of the share incentive awards granted in 2016.

        Equity in loss of affiliates was RMB208 million (US$31 million) in the six months ended June 30, 2016, representing an increase of 1772% compared with RMB11 million in the six months ended June 30, 2015, primarily due to the equity pick-up of loss of eLong, which became our affiliate in May 2015, in the amount of RMB158 million.

        Interest income increased by 72% to RMB342 million (US$51 million) in the six months ended June 30, 2016 from RMB199 million in the six months ended June 30, 2015, primarily due to the increased cash generated from financing activities in the second half year of 2015.

        Interest expense increased by 187% to RMB321 million (US$48 million) in the six months ended June 30, 2016 from RMB112 million in the six months ended June 30, 2015, primarily due to an increase of the loan facilities and the issuance of the Priceline 2020 notes, the 2020 notes and the 2025 notes.

        Other income amounted to RMB288 million (US$43 million) in the six months ended June 30, 2016, compared to other expense amounted to RMB4 million in the six months ended June 30, 2015, primarily attributable to the gain from the disposals of certain investments or RMB282 million (US$42 million) in 2016.

        Income tax expense in the six months ended June 30, 2016 was RMB147 million (US$22million), representing a 290% increase compared with RMB38 million in the six months ended June 30, 2015. The effective income tax rate in the six months ended June 30, 2016 was –8%, compared to –105% in the six months ended June 30, 2015, primarily due to the change of non-deductible share-based compensation expenses as well as the valuation allowance during the periods.

        Net loss was RMB2.1 billion (US$316 million) in the six months ended June 30, 2016, and net income was RMB17 million in the six months ended June 30, 2015. For the six months ended June 30, 2016, the consolidation of Qunar contributed RMB1.8 billion to our net loss.

        As of June 30, 2016, our primary source of liquidity was RMB15.6 billion (US$2.3 billion) of cash, cash equivalents and short-term investment, which include cash generated from operating activities, short-term borrowings from third-party lenders, as well as the proceeds we received from our offerings of convertible senior notes. Our cash and cash equivalents consist of cash on hand and liquid investments which are unrestricted as to withdrawal or use. Except as disclosed in this prospectus supplement, we have no outstanding bank loans or financial guarantees or similar commitments to guarantee the payment obligations of third parties. We believe that our cash and cash equivalents, our anticipated cash flow from operations, our credit facilities and proceeds from our financing activities will be sufficient to meet our anticipated cash needs for the next 12 months. We may, however, need additional cash resources in the future if we experience changes in business conditions or other developments. We may also need additional cash resources in the future if we decide to pursue additional opportunities for investments or acquisitions.

        Net cash used in operating activities amounted to RMB135 million (US$20 million) in the first six months of 2016, which was primarily attributable to (i) an add-back of RMB3 billion (US$448 million) in non-cash items, primarily relating to share-based compensation expenses, equity in loss of affiliates and depreciation expenses; and (ii) an increase in accounts payable of RMB1.7 billion (US$257 million), primarily due to the increased volume of transportation ticketing and package-tour services, as we generally entitled to certain credit terms from our suppliers. These increases were partially offset by (i) our net loss of RMB2.3 billion (US$341 million) in the first six months of 2016; (ii) a decrease in tax payable of RMB751 million (US$113 million), primarily due to the payment of individual income taxes for the exercises of stock options; (iii) an increase in accounts receivable of RMB515 million (US$77 million), primarily due to the increase of volume of corporate travel management service, as we normally provide our corporate customers with certain credit terms for the full payments of issued transportation tickets and issued and reserved hotel rooms; (iv) an decrease in advances from customers of RMB488 million (US$73 million), primarily due to more customer advances having been paid to us before year-end for bookings during Chinese new year; (v) a decrease in other payables and accruals of RMB302 million (US$45 million); and (vi) an increase in payment due from related parties of RMB469 million (US$71 million), primarily from Baidu.

        Net cash used in investing activities amounted to RMB1.8 billion (US$267 million) in the first six months of 2016, which was primarily attributable to an increase in investments and acquisitions and increased purchase of additional equipment and software, and offset by a decrease in short-term investments in bank deposits with original maturity of more than three months.

        Net cash used in financing activities amounted to RMB7.6 billion (US$1.1 billion) in the first six months of 2016, which was primarily attributable to (i) capital contribution or financing arrangements

in a total amount of approximately RMB6.5 billion (US$1 billion) in cash to certain non-U.S. investment entities; (ii) settlement of a portion of the outstanding 2% convertible senior notes issued by Qunar in June 2015 to certain institutional investors in the amount of RMB2 billion (US$306 million); and (iii) settlement by Qunar of its outstanding loan owed to Baidu Holdings Limited in the amount of RMB1.8 billion (US$274 million). These increases were partially offset by (i) the proceeds from short-term and long-term bank loans in an aggregate amount of RMB2 billion (US$305 million); and (ii) settlement by Baidu Holdings Limited of its outstanding loan owed to Qunar in the amount of RMB651 million (US$98 million).

        As of June 30, 2016, our primary capital commitment was RMB86 million (US$13 million) in connection with capital expenditures of property, equipment and software.
