Bigger planes carrying more people is the obvious answer
How does that one work to Leeds then? It doesn't, that's the whole reason BA were forced to do a 180 degree turnabout on the policy of all B737s to LGW and only B757s and B763s at LHR. Lost them a fortune, feed needs smaller aircraft and frequency to match O&D and connectivity. If you can't get that balance, you lose money. LHR is not DXB.
So, not
that obvious then?
