Middle East Options
It is said that frequency is everything. (Continental, now United, certainly seems to think so on the Newark route, those liking twin aisle aircraft might think otherwise.) BA's offer to certain middle east destinations such as Doha and Muscat does not appear attractive. Qatar operates four daily non-stops flights to Doha, BA a single one stop flight which cannot be attractive to the business traveller. Now that Qatar has joined OneWorld do you see this continuing? One problem with a codeshare is that T5 is full and a transfer to T4 is not ideal, but its probbaly liveable with.
Now that Oman operates a daily non stop from LHR might it be worth BA operating non stop with a 321? Some of the slots could come from reducing TLV to double daily.
