After the cheap jibes about 'spotters', we've had some sensible comments but I do commend the well articulated arguments by navpi, ozzi and Sioltach even if you don't agree with them.
Andrew H52 makes a valid point on the very high proportion of non-freight carrying flights but I would suggest that in a normal summer his 12 flights, mainly long haul carrying cargo in the belly hold, is on the low side even just for inbounds. Then there are the outbound loads.
I can actually understand MAG's policy in normal circumstances of concentrating freight at EMA or STN given MAN's constraints on slots and stands at busy times. However, I do think there should be flexibility to adapt that policy in the sort of situation that has prevailed for the last 9 months when I suspect J-I-T will have applied at times. I don't pretend to know the finances of acquiring or renting the necessary equipment for the airport or handling agent, or moving equipment from another airport, but with the number of passenger flights being relatively low, including those long haul flights that would normally carry cargo below, one would have thought there would be some money to be made from handling pure freight flights.
