When do flight prices change?
An airline will charge between five and 15 different prices for the same seat over the course of its shelf life. Advance prices will be lower, and as the flight fills up prices will increase. However, as the departure date looms airlines are likely to drop their prices dramatically in order to fill space - some money is better than no money, after allRachel England, journalist
When's the best time to book a flight?
There's a legend that exactly 21 days prior to departure is the best time to book for the cheapest deals, as it's at this point airlines will take stock of their empty seats and lower prices accordingly. It's also mid-week that airlines look at shifting remaining seats for upcoming flights, so wait until a Tuesday or Wednesday afternoon before bookingRachel England, journalist
What time of day is it cheapest to fly?
Flying late at night or very early morning will often mean routes are less crowded, but this can mean extended airport stays or arriving after or before hotel check-in. Airlines need to maintain a schedule during off peak times - try to make your weekend trip happen during the week and you'll get cheaper and quieter flightsJon Severs, journalist

Cheap flight tips
Well, we like to help you out, don't we? Here are some tantalising titbits to keep in mind:
- Be a bit flexible with your dates
Plane and simple
- If you check in on time but are prevented from boarding as the plane is full, the airline must offer you financial compensation
- If you're delayed for more than five hours, the airline must offer you a full ticket refund
- Advance prices will usually be cheaper
- Prices often drop just before the departure date
- Cheapest tickets for international routes are usually Monday-Thursday
- If you're flying in the UK, try to avoid Monday mornings and Friday evenings
- If you can, avoid peak times like summer holidays or Christmas
Things to remember
Make sure your passport's in date and find out whether you need a visa to go on hols - we don't want any disappointed faces at the airport.
You'll also want to triple check that you're flying to the right airport because that could get pretty awkward.
A lot of airlines allow you to check in online so if this is an option, you might have time to grab a cheeky pint/burger/souvenir at the airport - treat yo'self!
Finally, give yourself plenty of time so you're not dashing around before departure.
