单选题 The United States : Fliers may want to have their tickets in hand before catching their planes, but the amine companies are doing everything they can to bring forward cost-saving ticketless flight—no paper needed, just a ticker number and a photo ID (带照片的身份证). Anyone who buys a Northwest E-ticket through the airline"s computer service by June 16 will get an award (奖励). Next time you fly, you can buy another ticket for a friend for $99, going anywhere in the US or Canada through Feb. 12,2000, along with the lowest ticket prices. Some airlines offer extra frequent-flier miles for the ticketless crowd. And there are rising punishments for paper lovers. American, Northwest, United, and last week, US Airways have raised the cost for lost ticket replacement (替换) to $70 from either $60 or $50. The airlines insist that the increase in price is not meant to push travellers towards E-tickets but only covers the increasing cost of replacing and tracking a missing ticket.
