  • 第3题:

    Everyone knows airline pricing is based on supply and demand. Fares are mores expensive during peak travel seasons like summer and to prime destinations like European capitals. So if a flight to Rome costs more than a flight to Milan you d think that demand for Rome must be higher or supply lower
    What’s puzzling is that you can pay a high price to a given destination but a dramatically lower price for the exact same flight if you agree to go on to another destination.
    Take Alitalia to Rome for instance for travel in August A round-trip economy flight directly to Rome leaving JFK at 10:05 p.m on Alitalia 611 on August 5 costs $1,655 when booked on April 30 Compare that to $903 for a round-trip economy ticket to Milan(stopping in Rome)leaving JFK on the exact same Alitalia 611 flight at 10:05 p.m on August 5. So why is Alitalia willing to fly you to Rome for $752 less than it would otherwise plus give you an extra one-and-a-half-hour flight to Milan?
    Airlines have increased their profitability in recent years by segmenting the market for air travel and charging customers different prices for the same product. In this case the market is segmented based on demand for direct flights. Airlines know most people prefer the shortest route to their destination so they make customers pay up for the privilege of flying direct(They also make it a little more inconvenient if you don’t pay up for a direct flight in order to encourage you to fly direct)
    When process become so obviously illogical it may be time to why air tickets can’t be transferred or resold just like any other normal product If the airlines are entitled to exploit the free market shouldn’t customers be allowed to do the same thing?
    What is puzzling about the airline pricing to the author?

    A. Price for the same flight to a nearer destination is higher
    B. Prices for different destinations on the same flight are the same
    C. Price for the same flight to a farther destination is higher
    D. Prices for different destinations on the same fight are different

    答案:A
    解析:
    细节题。根据文段定位到第一段。我们可以知道这个一方面是建立在supply and demand,还有就是peak travel season和prime destinations,以及后文提到的destination。这样我们就得知在文段中提及的有B、C、D三项。但是唯独A项当中所说的成本和需求未提及。因此答案选A。

    Passage1When it comes to airline travel, perhaps nothing has revolutionized the passenger experience more than airline apps. Indeed, they' re becoming so ubiquitous that more than 50 percent of U.S travelers have at least one airline app installed on their smart device, according to travel industry research firm Phocuswright.Maybe that's because apps make travel easier, and often are more functional than a kiosk or even an airline's own website. Passengers report that they' re often more quickly informed of a flight cancellation or gate change than an airline employee. Not all airline apps are created equal, but in general you can use an app to check in for a flight, change seats, and request and pay for an upgrade. Road warriors in particular appreciate mobile boarding passes and the ability to track their flights. Many airlines now offer free onboard streaming entertainment via apps. The Delta Air Lines app even allows users to track their bags, from check-in to carousel, while the Air France app lets passengers download magazines and newspapers from the airline's library 30 hours prior to departure.But what if you are traveling extensively on more than one airline? Global airline alliances have their own apps that allow you to view flights for all member airlines and their affiliates, including code share flights. In general, you can find flight schedules for all member airlines and track member airline flights. Airport information is available, as are details about local weather at the destination. Where's the nearest airport lounge? The app will locate it for you.The Sky Team airline alliance app goes a step further by letting its SkyPriority members (Sky Team Elite Plus members and customers with first and business-class tickets) find out exactly which SkyPriority services-including priority check in and baggage drop off, as well as access to priority security lanes and boarding lanes-are available at individual airports.You' ll find that some alliance app features are available through multiple channels of communication. For example, Sky Team members have formed their own online community by sharing traveler tricks and airport tips accessible through a variety of channels, including the app, Sky Team's website, Facebook page and a dedicated tips site. Sky Team's YouTube page features travel tips from regional celebrities.Just as airlines seem to have conquered social media, another method of communicating with travelers has just arrived. KLM Royal Dutch Airlines is the first carrier to sign up for Facebook's Messenger chat app. KLM flyers can automatically receive itineraries, flight updates, check-in notifications, boarding passes and rebook flights and communicate with customer service, all from Facebook Messenger. Messenger for Business was launched so that customers-in this case, passengers-can transact business over the messaging app in a single communication thread. Roughly 80 percent of passengers on planes traveling within the U.S. have the Messenger app installed on their smartphones, according to Facebook.Clearly, mobile apps and social media have transformed our digital lives. Airlines favor apps and other technologies because they get customers out of airport lines and off phone lines. Through their smart devices, travelers now have untethered access to travel information. A few quick taps can supply individuals with information never dreamed possible even a decade ago. And with more people using smartphones as their primary computing device, and as more people own cellphones globally, people expect technology-driven methods of communication and convenience to accelerate. Whether you' re high-tech or not, you must admit that having immediate access to the information you need sure beats getting a busy signal on a toll-free phone line.According to this passage, which of the following apps provides priority services information for priority members?
    A

    The Sky Team airline alliance app.

    B

    KLM Royal Dutch Airlines app.

    C

    Global airline aliance app.
