现在坐飞机比以前便宜多了。为了适应通货膨胀，1955年从拉丁美洲到堪萨斯市的机票价格为575美元，今天却只需要200美元左右。现在许多人都有能力坐飞机了，但是却又许多额外的费用。下面是如何避过这些隐性收费的方法。
Flying is cheaper than it used to be. Adjusted for inflation, a ticket from LA to Kansas City cost $575 in 1955, compared to a couple hundred bucks today. Flights are more affordable these days, but pretty much everything costs extra.

一般情况下你付款的凭据是航空公司打印出来的金额。
There used to be a time that the price you paid for a flight was the published cost.
2.避免小件行李以及航空信用卡的行李费用。

如果努力想的话，我记得交运行李是免费的。现在，如果你交运自己的行李而不是单单将包裹带上飞机，几乎所有航空公司都会收取额外的费用。
If I think hard enough, I can remember when checking luggage was free. These days, almost all airlines charge extra if you check a bag rather than just carry it on your flight.
旅途助手提醒你下面这些航空公司收取的行李费用，第一个包裹的价格一般在25美元到75美元之间。例如，德尔塔、美国和维尔京在国内航班的第一个交运的包裹收费为25美元。勇气航空公司的打折机票一般情况下行李交运费会更高。他们的交运行李费用30美元起步，依据姓李的重量增加费用。西南航空公司是为数不多的免收交运行李费用的公司之一（但是第三件行李的交运费用为75美元）。
Trip Advisor has a full list of baggage fees by airline here, and prices typically range from $25 to $75 for the first bag. Delta, United, and Virgin all charge $25 for the first checked bag on domestic flights, for example. Discount airlines like Spirit typically charge more. Their checked baggage fee starts at $30 and increases depending on the weight. Southwest Airlines is one of the few to offer a free checked bag (the third one costs $75, though).
