When is it (supposedly) cheapest to buy plane tickets?
I hear about after midnight and Wednesdays, but all of this could be bullshit.
Surely we're talking in weeks? Not days and hours?
Lots to find on the web, e.g.:
In 2017, for flights within the continental U.S., 70 days in advance was the best time, on average, to buy your airline ticket.
However, this article is talking about Sunday being the best day to buy plane tickets.
Mind you, this is probably all US-centric. This is what I found about the UK.
