Fact:
I'm flying MAN-GVA next March on a Saturday on BA for 50GBP less than EJ LPL-GVA were quoting for similar times. The fares are there - you just need to shop around! People are flocking to EJ on the assumpton that they're the cheapest and ignoring the majors. Suits me, closer airport, free G&T's in the lounge & in the air.
Mind you - I could have gone for 20GBP less if I was prepared to treck to EMA for BMI Baby.
