I recently stumbled upon this too and found some cool insights! A lot of budget airlines release flight specials early in the week, often on Tuesdays. It seems like airlines modify their prices on Monday nights, so by Tuesday, you can spot deals. Also, setting up fare alerts on apps like Hopper or Skyscanner can be super useful. They track price changes and notify you of any drops or flash sales. Don't forget to check airlines' social media or subscribe to their newsletters for exclusive deals. I snagged a round-trip for way less than expected just by keeping an eye on these!
