Whilst, what you say is true tlv,cai are price sensitive!
other routes such as fna lowest fare £510 rtn gyd $619 rtn and others such as fru £359,ika £390,evn £389 all have quite high yielding fares in comparison to lets say jfk £73 rtn,ord £106,mia £118,sfo £172 (all vs)
I would say bmi are in a better position to ride out this present downturn than VS,BA and others who rely heavily on the good old us of a routes (which now they share with everyone ex lhr)
