Why the Vast Difference in Extra Fees Between BA and AA?
I'm using my British Airways Executive Club miles to do a LAX-HKG-DPS-BKK-HKG-LAX on Cathay in Business. I'm doing the DPS-BKK leg on Air Asia for a modest $89 each. The total taxes, etc. for the two of us using BA is $796.68. When I construct the exact same itinerary on AA.com I get $161.00 in extras. Why is there such a huge difference in extras going through British v. AA? If I were to pay for these tickets out-of-pocket the cost would be a whopping $16,357. I know I'm still getting a great deal, but I don't understand how there could be such a radical difference in extras fees. Can someone out there in FlyerTalk land give me a logical explanation? Thank you.
