Having had to recently buy a reasonably last minute ticket ALA-AUH-EDI, I noticed that EY's fares were pretty cheap and stable even up to the evening before the flight - only varying by (literally) a couple of £ from buying in advance.
On a side note, after I booked my ticket I discovered that EY are stopping the ALA and LCA routes from October - and blaming competition - which certainly doesn't fit with their "not caring about profits" image discussed here.
