MAN has told FR to sling their hook for very good reason. Yes LPL, BRS etc. are getting in the numbers with the locos but the airport is also a business.
MAN probably make more money off of the daily J passengers on the EK flights within the terminal than LPL do a day from all their FR passengers - it wouldn't surprise me.
It will be similar at BHX. CO and EK in the Midlands will be propping up the airport in these tough times with their lucrative passengers up front, as will LH, AF and KL. Forget WW and FR - they are just bolstering passenger numbers.
