Route Question

What is the max number of routes that the Game can handle for one Airline?

In the new version is it possible yet to fly say

dub-lhr-dub-lgw mtwhfss then say dub-fra mtwthss with the same aircraft (So two seperate routes on the route page)

The limit is not per airline, but just for the game as a whole, but seeing we just had a reset it will be some time before it is an issue again.

As far as different routes for 1 aircraft, that to my knowledge only works on alternating days, but I am not 100% sure, could also be that it is only 1 route per aircraft.
