Cabotage traffic in AS

According to ny understanding, in most cases other than special exceptions, it is not possible for an airlines to carry domestic traffic of other countries, even if the airlines have traffic right for individual segments.

For example, an airlines from Canada can carry traffic between SEA-YYZ and YYZ-EWR, but it can’t sell transfer tickets to passengers going SEA-EWR to transfer via YYZ.
Likewise, an airlines in Singapore can carry traffic between KNO-SIN and SIN-SUB, but it won’t be able to carry traffic between KNO-SUB. (Medan, Indonesia and Surabaya, Indonesia)
Or, an airlines at Dubai can carry traffic between DXB-CDG and DXB-RUN (Reunion), but with Dubai not being part of EU, they wouldn’t be allowed to sell ticket to passengers going from CDG to RUN.

A relatively fanous example in this is probably Asiana being fined for selling tickets that carry passengers between Continential US and Guam.

It seems like the restriction is not modelled in the game according to search result in ORS.

I think that, even if not for cabotage right, most usual passengers probably won’t pick an international flight that require carrying passport and pass through border control, when they otherwise wouldn’t need to

This is very much moddled in the game, but implementation differs per server afaik. Traffic Rights | AirlineSim Handbook

I still get such flight when searching in ORS in short term server, particularly when the search result is between 2+ interlining airlines which neither are in the specific country. Not sure whether it is actually being allowed or is it just ORS thing.

I have an airline in Hanoi and found great success linking the huge population centres in south east China with other parts of China via HAN. As it worked in game I assumed it was ‘legal’ IRL to the point where I had planned for a Canadian airline to link east and west coat USA via somewhere mid way between.

Not surprised it’s classed as cabotage IRL though in game it does present some great opportunities.

Another great example is linking Karachi with northers Pakistan with an Indian airline making a stop just over the boarder (at a station with no transfer capabilities I might add). I can’t see this being approved in real life.
