There is very little difference in the aircraft range and performance, as you say someone has to be last. Its not indicitive to the airport performance as BFS as well as EZY HQ LTN are also 700 bases.
ps on another note i was in Abu Dhabi this week where the DXB-NCL was getting good air time on local radio with special mention to Earl Grey! after all NCL is quintessentially english isn't it?
