Airline A has a rethink they don't want to end up with a "regional flight" whilst Airlines B + C end up operating from the UK Capital.
What's your moan this time? Airline A applied for MAN not knowing it was regional? Why must some people always link MAN with London. BOAC trying to stop all and sundry serving MAN and PIK then leaving both in the lurch is hardly relevant in today's market. Bang your head all you like it's not domination for fun and giggles it's domination due to a massive market in one of only three proper world cities.
BA and Virgin would object, for sure.
American, US, Delta and United might also object against A380s on their own turf, mainly as EK would pinch a fair whack of the point to point market putting a dent in their profitability.
