Which GDS offers all Info based on Booking Reference (PNR)?

Question

Hello,
I am new using GDSs and I am trying to get response to the FlightOrder Management API from Amadues
https://test.api.amadeus.com/v1/booking/flight-orders/RE88ST
I get a NOT FOUND response.
My question is: It is because such information requires extra permissions from the airline?
I am investigating wich GDS would suit better. Your article (https://www.altexsoft.com/blog/travelport-vs-amadeus-vs-sabre-gds/) is great!!!

Hi, Francisco!
Thank you for your question and feedback
First of all, let me draw your attention to the fact, that from API point of view your request is not correct. {flight-orderId} you can see in Amadeus API reference for bookings management is not a PNR. This is an order ID, you can find this order ID in /booking/flight-orders response when you create a booking using POST verb. This is Amadeus internal identificator that is required to get PNR information using self-service or enterprise REST API of Amadeus.
However your assumption about access issue is also correct. You can not retrieve any PNR from GDS without appropriate permissions and not always PNR that passengers see on their tickets are the same PNRs that can be retrieved from Amadeus. If several systems are involved in the booking process, (say, an OTA booked a flight via Sabre, but an airline operating the flight hosts its CRS in the Amadeus system), each of them generates its own booking reference to the file with flight details. 
So, to work with a certain flight order in Amadeus, you have to enter the record locator (6-character code) returned particularly by Amadeus  &mdash; not the PNR number you see on the e-ticket or in the booking confirmation e-mail.

Hi Ivan!
Thanks a lot for your answer. I really appreciate your time and disposition ????????
I need some guidance and support here, since I am trying to solve a project my company is facing right now. 
I explain, in case you can help me out in any way.
The issue...
 
I am building an app for an airline X that shall get the booking reference of a flight booked by the client, and based on that information, the app shall get specific information: 
- Flight Information
- Personal Information of the passenger(s)
- Bag allowance ==> How many bags can be checked in
We can assume that the permissions from the airline are granted.
 
I thought this check could be done with a GDS like Amadeus. Or since I would be working directly with the airline company, I don't need a GDS in between?
 
I really appreciate your support and look forward to getting your feedback from this message!
Take care Ivan and have a nice day!
 
Cheers,
Francisco
