Well if that the question that playing in your mind, then I think you should ask Tom Parsons regarding this. I am serious you know!
If you want to travel this spring or summer, the next couple of weeks should be a great time to buy tickets. Based on what he said, the war of bargain fares usually happens after the spring break and Easter travel season ends. From here we can see sales for travel within the continental U.S., to the Caribbean and maybe to Hawaii increase.
You may have to be flexible to get the best prices for the summer. Check prices for the days you want to travel, then compare fares for departure and return on a Tuesday or Wednesday. Saturdays are usually the next-cheapest day to travel.
Mean time, if you are thinking about traveling to Canada, you can look at U.S. airports and drive across the border. Consider Buffalo for Toronto; Burlington, Vt., for Montreal; and Seattle for Vancouver. When renting a car, make sure you can take it across the border and that you have insurance.
Europe flights will be a much better deal for travel in April and May. If you are set on summer travel, you could be looking at double or triple the cost. Check flights from the U.S. to London, and connect there, or consider a train for travel within Europe.
Thanks a lot Tom!
