AA ticket, AY Codeshare, BA Metal
My husband is traveling in a couple of weeks JFK-LHR-TLV in Club. Ticket was booked through AA (AA ticket number). The JFK-LHR is an AY codeshare flight number on BA metal, connecting to LHR-TLV (BA flight number / BA metal). He is able to select a seat for the TLV-LHR flight (for a fee of course as he has no status) but not for the JFK-LHR.
Wondering if anyone knows a way to select a seat in advance for a BA flight booked as AY codeshare? Have tried the Finnair website without success. Has anyone managed this?
And if not, will he be able to online check-in at T-24 and select a seat? Or will the AY codeshare require airport check-in?
Any experience with this situation greatly appreciated.
