I flew EI direct DUB - MCO last Summer with no problems, saved a lot of messing by not goin BA or someother airline!
Last time I flew BA we had to get a connection to Heathrow to catch our mode of transport (BA 777, Oh yeah

) to MCO, little bit awkward as you have to go backwards first. On the way back with EI there was a pit stop made in Shannon, didn't care as it was another opportunity to experience T/O and the joy of flight in the 330. The thing is though I remember there was rumour as to whether EI will be operating this route in the near future, thats what I heard anyway.
Where in Florida is it on? Florida is a great place to do some flying, not too much in the midlands apart from a huge croc infested lake namely Lake Okeechobee, nice water feature all the same. Flying along the coast is beautiful and would really recommend it if you got the chance.
