According to this Guardian report, you may not have a better chance to book for your holiday if you don’t do it now.
The report says:
Fall may have just arrived, but it’s already time to start planning for the winter holidays.
If you want to save money on airfare, that is.
Flights can cost up to 75% more at the end of the year than during non-holiday times, so booking travel before winter arrives can save you hundreds of dollars.
