I have an existing AONE4 which I started a while back, and will be stopping it in LHR for a while. I was planning to go to TLV, however the aircraft has been downgraded to a 767. And now that BA has the flight to MLE, I am thinking of changing it, but can I do so per the rules of the RTW ticket? I know MLE is in Asia, as is TLV and DXB. Besides giving up 2 segments to travel out of LGW, can I make the change? Thanks in advance for your help!
