'paddy'
I used BA from LGW to MCO in 2006 and 2007 and had no security check on arrival.
I queried the present situation re EI PAX having to clear security with an MCO official and his reply included the following -
'Unfortunately due to the major construction project taking place on Airside 1 (Gates 1-29), we are currently unable to provide for the sterile transfer of international passengers to the Main Terminal which previously avoided the requirement for a security check for international arrivals. We hope to resume this ability and return to the former level of customer service as soon as construction allows. At that time, you will also see major improvements to Airside 1, much more inline with what you are familiar with on Airside 4 (Gates 60-99)'.
EI use Airside 1 gates; BA and Virgin use Airside 4 gates.
So it looks like EI PAX will have another 12 months or so putting up with the TSA on arrival at MCO.
Incidentally the TSA have agreed to let in sealed duty free purchases and not confiscating all that lovely Baileys, Paddy etc! Nice of them eh?
