If you fly business class, you can usually save by waiting to upgrade at the airport
如果你要坐商务舱，你可以先定经济舱，到了机场再升舱，这样通常更省钱
I know it might sound strange, but I always advise everybody to purchase an economy ticket at home and upgrade it at the airport. Opting for an upgrade will drastically reduce the price of the ticket.
As soon as you purchase your economy seat, you may start receiving email deals to upgrade your ticket but don't rush. Wait until you get to the airport and ask for an upgrade at the counter.
一旦你购买了经济舱机票，你可能会收到让你升舱的电子邮件，但是不要着急。等到了机场再去前台请求升舱。
Sometimes, if the plane is empty or you have a loyalty program with the airline, the gate agent can upgrade you to business class at no additional cost. But even if you have to pay, it's still going to be much cheaper than buying online.
Just be extremely nice to the staff and arrive early so business seats are still available. But don't wait until you get on the plane — flight attendants don't usually have that much power.
If you're flying internationally, it's best to finish any food from your first destination before landing since some countries don't allow fresh foods through customs.
You can find better deals online than at the duty-free shop
在免税店购物没有网购便宜
Duty-free always attracts passengers at the airport, but the savings aren't as good as they seem. Some airlines also have duty-free catalogs onboard where you can shop in the skies. But those prices are even worse.
You can find much better deals online if you take the time to look.
如果你花时间慢慢找，你完全可以在网上用便宜得多的价格买到同样的东西。
It's almost never worth it to exchange money at the airport
在机场换外币非常不合算
Too often, people land at an international airport and realize they don't have the right currency. But the airport is the worst place to exchange if you want a good rate.
人们在到达国际机场时往往会意识到自己没带外币，但是机场是兑换外币最不合算的地方。
Most banks or shopping malls have currency exchanges with steadier rates if you remember before your flight. And if you forget, just get enough money for a taxi into the city and go to a local bank.

I know it might sound strange, but I always advise everybody to purchase an economy ticket at home and upgrade it at the airport. Opting for an upgrade will drastically reduce the price of the ticket.
我知道这听起来可能有点奇怪，但我总是建议所有人在家先购买经济舱机票，到了机场再升舱。选择升舱会大幅降低机票价格。

有时候，如果飞机上座率低，或者你是该航空公司的会员，检票员会免费给你升商务舱。不过即使你需要付费升舱，也比网上购买商务舱机票要便宜得多。
Just be extremely nice to the staff and arrive early so business seats are still available. But don't wait until you get on the plane — flight attendants don't usually have that much power.
你只需要对工作人员彬彬有礼并提早到达，以免商务舱被订完。但是不要等上了飞机才要求升舱，乘务员通常没有这么高的权限。
Never waste money on bottled water at the airport
不要浪费钱在机场买瓶装水
You can't take liquids through security, but no one said you can't take an empty bottle.
你不能带液体过安检，但是你完全可以带空瓶子。
Most airports are full of water fountains, and many even have a special pump to refill bottles quickly.
大多数机场都有饮水器，有些机场甚至有快速将水瓶装满的直饮水龙头。

The same rule applies to airport food
在机场买食品也很浪费钱
For some reason, people have a fear of bringing food through TSA security. But it's a great way to save money, as long as it's solid, like a sandwich.
出于某种原因，人们总是害怕带食品过安检，但是自带食品是省钱的一种好办法，像三明治这种固体食物都可以过安检。
If you're flying internationally, it's best to finish any food from your first destination before landing since some countries don't allow fresh foods through customs.
如果你乘坐的是国际航班，最好在飞机着陆前将你从出发地带来的食物吃完，因为有些国家不允许生鲜食品过海关。

机场的免税店总是能吸引不少乘客，但是免税商品并不像看上去那么合算。有些航空公司甚至在飞机上出售免税商品，但是这些免税商品的价格更加高昂。
You can find much better deals online if you take the time to look.
如果你花时间慢慢找，你完全可以在网上用便宜得多的价格买到同样的东西。

如果你在乘机前记得换外币，大多数银行或商场的外币兑换点汇率都更稳定。如果你真忘了，你可以先兑换一点外币足够你打车到市里，然后再去当地银行兑换。
