However, you confuse e-tickets with real connections or tickets booked separately on the same route, which is part of your problem. ITA Matrix can`t find a route for this though, and I guess it`s due to issues with interline agreement. But this brings us to the bigger question: which airlines on a route need to enter into interline agreements to book an itinerary? In case of problems, always check if there are flights on the route made by another company (codeshare). Airlines that participate in airline alliances such as Star Alliance, SkyTeam or oneworld almost always have interline agreements. However, direct competitors may also benefit from interline agreements. It can happen. Airline A has an interline agreement with B and C, but B not with C. If the ticket is issued by airline A for connections B and C, you can have this situation, a ticket, but no luggage by check. Again #6, if something happens and you miss the flight, security will be provided by the ticketing airline (company A in my first example or BA in the second). So you need to know who the ticketing carrier is, as you may need to contact them if something is in the event of a problem. It may also mean that you will be redeployed to the source (Dublin) or Manila for the return if you know that the first flight will be delayed.

No, it doesn`t work that way. If it is an itinerary, you will receive a ticket. This is all part of the airlines that interconnect with each other (I used to work for an airilne) Small legacy carriers usually have interline agreements with large network carriers heading to their markets. Most low-cost airlines, which only sell directly to consumers (and not through global agencies or distribution systems), do not support interlining at all. Important: Airline agreements must not be reciprocal. One of the latest codeshares announced is, for example, between Lufthansa and Vistara. Lufthansa serves Delhi, but has no network inside India. This codeshare allows passengers to book directly from any Lufthansa destination to a number of new cities in India, including Ahmedabad, Bengaluru, Goa, Hyderabad, Kochi and Pune.

This is a development of an earlier interline agreement between the two airlines, which involves a deeper relationship. 2. To check the interline agreement between two airlines, enter: TGAD-YY/ZZ (YY being the valid airline and ZZ the second airline). Is it true that the marketing carrier must have interline agreements with all executive carriers? Or can you book a flight if all airlines have an interline agreement with at least one other airline, but there is no airline that has interline agreements with all other airlines on the route? How does it work for an American flight? However, during the presentation in Dublin, I was told that I had to drop off the luggage at LHR again, as there was no interline agreement between the airlines. 6X and YY have an electronic ITA, which makes it possible to obtain an E-Ticket on the LH plates. However, flight 6X is operated by another airline (another company) and the issuance of 6X tickets is therefore refused. This is the situation in which you have Carrier XX followed by Carrier ZZ, which is booked by TT, which is not with both interlines, but XX and ZZ interline. It is possible, but XX cannot check you in for the ZZ sector, there will be no transfer of luggage from XX and ZZ, and ZZ will not receive notification if you are delayed or harassed by XX. Worse still, XX does not have the legal authority to change your ZZ flight coupon and therefore no way to reinstate you on a subsequent ZZ flight, and may refer you back to TT to make further changes to the ticket. I think most travel agencies would refuse to issue a ticket that would include a route between two non-interlined airlines.

An interline agreement, also known as interline, online ticketing, or online booking, is an agreement between two or more airlines to process passengers if their itinerary involves travel with multiple airlines….
