What is the best day to buy a plane ticket?
This just in! Airfares offered on Thursdays tend to be the cheapest, according to flight demand on Travelocity in 2021.

In 2021, flights departing on a Monday were generally the cheapest of the week, whereas you may pay a premium for weekend flights when demand is usually high. On average, tickets were most expensive for Saturday departures, so if you need to fly out on a weekend, you might look for deals ahead of time.
How far in advance can you book a flight?

"We felt the charges for the drinks and snacks were excessive, but if someone wants to eat or drink at those prices that is up to them. However, charges for just touching an item or moving it slightly were petty and insulting. For that reason only, we gave you a four star rating instead of five."
