Hi,
I have flown with Airtours/MyTravel from Belfast many times to Sanford, Orlando. IMHO the flight is basic with no frills - nothing is complimentary. Also the prices are just as expensive as with anyone else and also because we fly from Belfast it is always more expensive - 2003 is about £1000 more than this year for my family. Airtours seem to have the monopoly on Belfast so they think they can charge whatever they want.
As for the upgraded seats. We have seen them several times and I do not think they are worth the extra for our family (£600 in total). There is some extra leg room but not an awful lot. The only other extras are the complimentary drinks. We upgraded with them a few years ago for £89 each but the plane was a larger one whereby you could lie flat out - not as now. If this was the case I would upgrade but there are a lot of things to spend £600 on in Orlando.
Last year we flew with Delta from Dublin and they were excellent with more leg room and everything complimentary and also their air hostesses were IMHO a lot friendlier.
One thing we always notice with Airtours is they never have any change when you order drinks or duty free. This is very annoying and I wonder if anyone else has also noticed this. It seems to happen all the time.
Since I prefer a direct flight I put up with it however next year seems unlikely due to the prices.
Upgrade if you really need the extra leg room but I do not think it is worth £600 for a family of 4.
