Other benefit of this type of agreements is the easiness to purchase flights of other airline in the same ticket, if they share a connection point with Interjet. So,the passenger only needs to check in with the airline that operates the first leg of the trip and can pick up his/her baggage at the final destination.
Is important that you take into account the travel policies of our allies (baggage, pets, pregnant women, unaccompanied minors, etc.), which can vary in relation to Interjet policies.
There exist several types of agreements between airlines, amongst them, the codeshare flights and the interlinear agreements.
