When I flew home for Christmas, I bought my tickets in October for around 340 dollars round trip. With only 2 weeks left the same tickets were right around 200. I think it really depends on whether or not the flight is full, or needs filling. They'll usually drop the prices closer to departure to fill all the seats.
Well it depends on what time your going to depart and arrive, what day your going to depart and arrive and what month your departing and arriving and where are you going.
Weekends are peak days so don't choose to travel on weekends, travel on fridays or weekdays. Peak months are mostly Summer and Winter Vacation.
The best time to buy a ticket to avoid loss of seats, book your flights at least 4-6 months before travel. E-booking and Online Check-in avoids queues in travel agencies and lets you choose seats and order special meals through E-Check In.
Well back to best time to buy tickets,
Actually in tuesday midnights to wednesday 1 am through E-booking in websites of airlines. This is because the airline computer system gets rid of all the reserved flights that were not sold.
Don't go last minute shopping or booking because it is more expensive and loss of seats may be possible
Very late at night or super early in the morning.
Good deals for traveling on Friday the 13th.
Try numerous websites and airlines.
Are you flexible on airports you leave from? It can mean a substantial financial difference.
On Pricleline.com you can request the price you want to buy the ticket for and sometimes you get.
Update: News report said that Tuesdays & Wednesdays are the best buying and flying days.
Some airlines will give you a credit if you buy the ticket early and then the rates go down.
You have to ask prior to buying the ticket and follow the rules for getting your credit.
There is no hard and fast rule about this. However, you are trying to fly to a popular holiday destination during school holiday period, so in this case the answer would be to do it sooner rather than later. These flights are likely to be well filled, so with few empty seats there is not much chance of last minute deep discounts.
If you were flying to some place in the north-central USA in February, it would make sense to wait till almost the last minute.
Book at least 21 days in advanced, the earlier the chaper.
Go to sites like cheaptickets.com, orbit, expedia and shop around. Fly on less travled days like tuesdays because you can save money that way...weekends are usually most expensive to fly.
try www.bt-store.com it gets me the cheapest rates usually.
another trick you can try is changing your flight date one day ahead or earlier. i once booked a flight for the same week and ended up leaving one day early cuz it was $200 cheaper for some reason!
