When I go to Alaska airlines site and search for a itinerary with using miles checked (award), I get 3 airlines' flights - Alaska/American/Delta..
1) So can I use BA avios (by calling BA) to book any airlines' award flights shown on Alaska's site or only Alaska will work?
I want to fly domestic within USA using British Airways avios. I know I can book American award flights on BA site. But these days American has very bad availability on all domestic flights.
2) Is there any other way I can use BA avios for domestic flights except American?
