Question

12．With fuel costs rising and airlines finding more fees to impose （強加，征稅）on travelers every day，airfare isn't getting any cheaper．Since you can't drive to all your dream destinations，flying is the only way to go sometimes and，undeniably，the fastest．Luckily，there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead．
Get the best fare．Airlines put out their fare sales on Tuesday morning，making this day the best day to book a flight for less．
Fly during the least popular times．Tuesday，Wednesday and Saturday are the slowest days to fly，which means cheaper deals than the rest of the week．You can also find reduced rates on early morning flights，since many people don't like to get up before the sun to get to the airport．Earlier boarding times can also considerably cut down your chances of getting bumped on an overbooked flight or delayed because of other delayed flights or mechanical issues．
Choose your seat later．Some airlines charge you to pick your seat when you book online，adding even more to the bottom line of your ticket cost．If you show up early on your travel day，you can still get suitable seats．Some of the best seats get held back until flight day，unless others are willing to pay extra for them ahead of time，so you still have the chance at one of those．
Fly on holidays．You already know that summer is the most expensive time to fly，and even though most other times are more affordable，the days surrounding holidays can be crazy．Save big if you're willing to travel on major holidays，such as Thanksgiving and Christmas．
Don't wait until the last-minute to book．Many travelers don't know that there's a sweet spot for booking and getting the best price on your tickets．Book too early or too late and you could end up paying more than you need to．The best time to book is between three months and six weeks from when you want to travel．
