I think that's possible, absolutely.
As we always say, you have to make life easy for tourists. If a trip looks complicated to them, they will change destinations or travel plans.
Unfortunately, connecting flights or the routing that an airline company offers is often complicated. However, if airlines co-operated, that would make life easy for tourists and help increase travel to the regions. From a market standpoint, co-operation between airlines would obviously be difficult, but it's the way to go if we want to promote tourism.
