PNRs are not maintained by airlines themselves, they use GDS like Amadeus or Sabre to do that. They still go through mainframes.

- tyingq 5y ago>PNRs are not maintained by airlines themselves This isn't correct. You can have a PNR in a GDS, but you don't have to. The airline has their own central reservation system with the authoritative PNR. The CRS may be provided by Sabre, Amadeus, etc, but it's not a GDS...that's separate. >They still go through mainframes Some have moved entirely off of TPF mainframes. Amadeus/Altea is one example.
