I am trying to ticket the following through BA:
1. KHI-DOH BA (operated by QR): transit
2. DOH-LHR BA (operated by QR): transit (as less than 24 hours in London)
3. LHR-DXB BA: stopover
4. DXB-DOH QR: transit
5. DOH-MIA AA (operated by QR): transit
6. MIA-JFK AA: stopover
7. JFK-DFW AA: transit
8. DFW-ANC AA: transit
9. ANC-DFW AA: transit
10. DFW-MIA AA: stopover
11. MIA-LAX AA: transit
12. LAX-HKG CX: stopover (AA not available in D)
13. HKG-DPS CX: stopover
14. DPS-HKG CX: transit
15. HKG-CMB CX: transit
16. CMB-KHI UL

The quote provided is 6253GBP, out of which 3449GBP is the base fare. This is correct. YQ is around 914GBP and YR is around 698GBP. RGGA (whatever that is) is 922.90GBP.Fare - £3,449.00

This feels quite heavy on YQ/YQ/taxes. I also have no idea what RGGA is. Any suggestions what I could do to reduce these? I know I'm going through LHR but have already limited this to a transit. I'm crediting to AY.
