When buy flight tickets and when are airline tickets the cheapest? The observations show that it’s not worth booking airline tickets on weekends, especially on Sundays. It’s the time when most people have time to look for flights and airlines increase their prices.
A better idea is to look in the middle of the week, especially in the morning – If it’s possible, be flexible with the departure date. You can find out that a more attractive deal might be available the day after the planned departure.
