I was able to grab a TPA-LGW for $446.30 (260.00 + 186.30 taxes and fees) yesterday for Apr 8 - Apr 12. I just went out there today and priced the EXACT same trip and it's now $1,686.30 (1531.60 + 154.70 taxes and fees). And the price difference isn't just on the flights that I'm on. It's all across the board from $1686 to $1982 on flights where the max was around $850 - $900 yesterday. Can someone please explain the logic behind this type of jump in pricing? From comparison on expert flyer and seat maps, it doesn't look like that many seats were sold yesterday on any of the legs...
