Both TUI and Flybe have flights from Alicante to DSA, and both are generally very expensive. However, I can see that the TUI one-way flights to DSA on Dec 23 and 26 are now just 39 quid. FlyBe, on the other hand, is keeping its prices sky high. Virtually all FlyBe's one-ways are way over 100 quid, and the prices don't even seem to change during the "summer sale" which starts in March. It seems like TUI is willing to drop its prices at the last minute to fill its planes, but FlyBe isn't. It's a popular route, but with Ryanair flying ALC - EMA for peanuts, I can't see FlyBe's pricing policy as being sustainable.
