a spread of £16-50 - £171-50 (one way, not incl taxes) for a day six months hence sounds like a bit of a lottery to me!
I guess what I meant, jumpseater, is that you cannot predict with any confidence what the fare might be, even booking six months in advance.
The unwary punter who pays £279.90 return on EasyJet (when she could have paid £130.70 return on BA (dearest fares the respective carriers quoted on the dates I selected)) might consider LCA fares to be a lottery - that is my point
