WHBM
Transatlantic - agreed
Toronto - in summer supports AC daily plus Transat (and some Skyservice I think?). All that and Zoom putting 763ERs into BFS. The Shannon stop has to be a big problem economically. Need a smaller aircraft than a 332 when the competition into DUB/SNN are using 310s and 762s.
Orlando - could refit a 330 (during your $10m refit) to charter config (with a small "club" cabin like Transat et al) for Orlando and some Caribbean work.
Dubai - no way unless Emirates are on board and CX picking up at DXB (they do) and QF (they don't).
Transfer traffic - can't really move on because otherwise you play into MOLs hands who doesn't give a damn if you miss a connection because he won't transfer your bags anyway. It needs to get done.
New types - should only be gotten if they have a business case. Why order 767s TTT when the 330 is in the same general class, and EI already struck out with the 763ERs before.
On the other hand, 752 or 753 with Continental style winglets and a very small Premier cabin would make more sense because the 321s won't go transatlantic and AA are showing the way - 767 to DUB and 757 to SNN. Toronto could work in the winter *if* you had 757s. If EI served all ports ex SNN with 757 and the thinner US DUBs, fewer 330 cycles and capacity that made sense would follow along with more 330 eastbound possibilities.
Lastly - the 320s. EI have six options on 32x, make them heavy 319s and use them like AC does, proving routes and handling longer thinner routes. Could then let some/all the 321s go (to IB, say, especially if 757s came the other way) and tighten the LHR yield with 320s, especially if you actually have a long haul strategy which is not to mimic BA's (i.e. everything into LHR).
Finally (not to WHBM) for those seeking 777s - first, GE Capital would need to be making a stupendous offer (in exchange of EI going GE, natch). They don't need to because Boeing don't have any problem shifting 777s, they need help shifting 744s which EI will never take.
But why? It's a huge change of equipment and the 787s won't be arriving for a long time so you end up with a split fleet and no easy progression from the 32x fleet. EI is not like AC, where Boeing was offering equipment in sectors Airbus couldn't match, like 777F and replacing their huge 762/763 fleet.
