LAX to KOA
 

Already booked BA LHR to LAX using Amex 2 for 1
Want to book onwards flight to KOA. I guess best to choose AA as it is part of one world.
Will our BA Gold give lounge access at LAX and or KOA?
Should we book through AA website or can we book through BA?
Finally any suggestions for rental car with full insurance from KOA

BA Gold will get you into Qantas first lounge as well as AA Flagship lounge in LAX. Qantas has nice table service but no view. Flagship has better views and ok buffet. I don’t think there’s a Oneworld lounge in KOA.

You’ll have to book with AA as you can’t book a purely domestic US trip on BA.

KOA is mostly open air as it’s Hawaii
there isn’t a lounge there. You go to and leave the planes by walking on the runway
But it’s Hawaii and it’s beautiful

we use Avis for cars but all major rentals are there

Paul611 , note that oneworld member AS (Alaska Airlines) also offers nonstop service between LAX and KOA.

Are you planning to fly First Class or Economy between California and Hawaii? If Economy, note that your BA status would get you free Main Cabin Extra (extra-leg-room) seats and free checked baggage on AA -- even if you were to book AA's cheaper "Basic Economy" fare.

Best to stay off the runway. ;)

The return times from KOA are pretty tough, I’d consider a hop to HNL and back from there on the daylight onwards to LHR from there

But, KOA is also on the hot and dry side of Hawaii, so being open air isn't always great when you're standing around in the sun waiting to board.

As above Alaska AS in a oneworld airline. AS now own Hawaiian HA which at some time will be a OW airline and fully integrated into AS

Just to mention, if you go via DFW you will get a full long haul plane with lie flat business seats rather than the "normal American domestic seating" - they have two flights a day to HNL and one to KOA from memory.

At this point it's probably not worth going backwards/forwards, but it is a far nicer experience, and DFW has a good flagship lounge with a nice view of the airfield.
