Instead, it’s much more effective to start tracking flight prices several months before you travel and set up price alerts on comparison sites like Google Flights, Skyscanner and Kayak to make sure you’re getting a good deal.
A well-worn travel legend says that Tuesday is the best day to book, because airlines often release sales starting from Monday night or Tuesday morning.
Recent data from Google Flights suggests this may be partly true, with historical prices showing Tuesday to be 1.3% cheaper than the most expensive day to book, Sunday.
But this doesn’t mean booking on a Tuesday guarantees you a good deal and, in reality, there is no cheapest day of the week to book flights.
Airlines use dynamic pricing, which essentially means fares rise and fall according to the number of tickets sold and the time left before departure, making it hard to predict when the cheapest day will be.
