For many people, the best days for air travel are probably the ones with the lowest fares and the smallest crowds. Knowing when to book your reservation can help you land a flight that matches your preferences in both categories.
If your priorities are saving money and dodging the masses, the best days of the week to travel are Tuesdays and Wednesdays.
People rarely think of holidays as a good time to travel; however, there are exceptions. Although airlines are sold out on Christmas Eve and the Wednesday before Thanksgiving, the actual holiday may be a good time to travel.
The further ahead you book your flight, the lower the fare tends to be.
Peak and Off-Peak
Popular vacation destinations tend to carry more expensive fares during peak season and less expensive ones during off-peak times. This is especially true with international flights.
According to Farecompare.com, fares are the cheapest on weekdays at 10 a.m., 12:30 p.m. and 8 p.m. Eastern Time and on weekends at 5 p.m. These are the times when the airlines load new fares into their reservation systems.
