Looking at booking return flight from IAD to SYD mid April return early May
I noticed Kayak had cheap fares using Qantas/AA so went to the Qantas website and noticed a couple of things.
1) Qantas offer both AA and United flights on the internal US legs - AA is codeshare I think because of the 4 digit flight number and United's are quoted as the regular 3 digit flight numbers.
Why is that?
I thought that because Qantas and United are in different alliances that only AA would be offered by Qantas internally in the US.
2) Also, although price differences don''t really bother me that much, Kayak was cheaper by about $90 than directly thru the Qantas website (I know Qantas will charge a cc use fee so that total goes up too, not sure about Kayak)
Kayak also offer a Qantas/United/AA combo as per Qantas website
My main question though is how come United flights are offered by Qantas on their website?
