1) Would there be enough support in one of the worlds where it is possible to open 1 (maybe 2) foreign hubs.
Hub must be in one of your alliance partners home based airports
Hub can have a maximum of ..?.. gates (not too many i would suggest)
Most alliances operating here are not really alliances in my opinion. The bigger the better seems to be the deal; which is far from efficient.
2) Would it be possible to configure planes with a fourth category seating (comfort).
3) Open a lounge in your terminal and provide ground service?
