How much time in advance is ideal for getting the best price for plane tickets?

Question

For tickets from NY to Europe in the summer(Germany)

Answer 1

usually about 21 days for domestic, but more for international maybe like 30 days.

Answer 2

The *best* time is to change your trip to a winter one. Summer prices to Europe suck.

But buying your tickets in February is best for a summer trip to Europe.

Answer 3

At least two weeks. Anything beyond that just depends on the kind of sales they are having. Less than two weeks and you're screwed.

Answer 4

As soon as you know you are going and the dates. The furhter in advance the better off you are. You may find deals last minute, but there is also the chance that it will be a lot more expensive, or you won't be able to get anything.
