I am in favour of expansion being designed to benefit multiple airlines rather than one.
However, I am against the idea of exclusive rights for an entire airport, since it can lock out other airlines, specially in the later phases of the world, which can severely limit the progress of newer airlines and airlines based in countries with very few airports
I wish that the idea of exclusive rights for an entire airport would be a thing only in servers with no political restrictions
If you wish to implement the idea of exclusive rights for an entire airport everywhere, then please not without some loosening of political restrictions for airlines based in countries with few airports, which may or may not include PIASA , ASEAN single aviation market and/or ECAA with the addition of the new partners
Addition of nearby “subtitude to the main one” airports to cities will also be welcome. travel math can help find additional airports for certain areas, here’s for Lima, for example
