  • Tip: Tuesdays, Wednesdays and Thursdays are the cheapest days to fly in January and February


March and April



  • First post-winter price hike: Feb. 29 through March 1. It's still a good value, but not the cheapest time to fly.
  • Most expensive time to fly:Avoid Fridays and Sundays; they're more expensive.
  • Tip: The cheapest days of the week to fly are Tuesday and Wednesday.
