The London route will be popular as people are ticked off having to go via another city to get there. Same if I have to go to Europe.
My pet hate is the MCT - DXB short hop and then on to somewhere else. Lufthansa and Swiss do it with KLM going Bahrain, Abu Dhabi and then Amsterdam.
BA flights are reasonable thank god.
Rumour has it that Air France are starting CDG - MCT soon. But again, I'm not sure if it's the via DXB thing.
