Qatarman,
Yes they will still be Aldo Zilli meals, however will have a more normal influence and will be "inspired" by him.
Lee9371,
When you say "old" when was the last time you travelled on either airline?
Thomas Cook use A330, which all(inc ex My Travel A330's) have 33" in economy and 35" in Premium, the layout is predominantly 3-3-3 on these aircraft, a lot do not like this layout but it may suit depending on your party size.
Thomson Airways will be using what was the ex-Thomsonfly aircraft on the Orlando routes these have 33" of legroom, versus what was 29-30" of legroom, Also in economy they are configured 2-4-2 which more people prefer over the 3-3-3 configuration, both have similar elbow room, it is only the ex-First Choice that have better elbow room but you would need to travel to say Birmingham,East Midlands or Bristol to get these aircraft on this route. Premium is worth it personally I think Thomson is only £130 each on this route in the summer from Gatwick, so worth it, when you consider the same service is £300 on other flights of similar length.
