Cheers for the replies guys. Been trying to get sample rosters for months, but with no luck. I do understand that the 380 vs the 777 with EK is very different, and both of those are very different from EZ @ LGW.
Personally, the thought of 4 sector days for the rest of my working life with a constantly alternating pattern between earlies and lates fills me with dread. Although the money with EZ sounds vaguely sensible (at least for a UK based job).
