Off the top of my head. Ryanair, EasyJet and Jet2 are all currently taking DEC's. That's without doing any research.
Hmmm, right, let's see... So you can swap jobs, because all those people in the LHS are leaving for the Middle East in droves as they've had enough of 4 sector days and 900 low cost short haul hours per year with 20 minute turn arounds?
When do you dumbos realize that it's one giant game of musical chairs of chasing quick money, chasing quick upgrades, and chasing quick shiny jet ratings? And it's not only that the chairs get fewer and fewer, they also get smaller and smaller in terms of T&C.
My advice: buy a house which fits your wallet and not your ego.
