On BA I found Air Berlin TLV to NYC booking with Avios. After the payment page. I get a "sorry we're unable to complete your transaction" message. I called BA and they say they don't see availability on the BER to NYC segment, and can't book it for me. They said, it appears on the website because it probably didn't refresh their availability yet. But for 4 days now the BA website still shows availability, but I still can't complete the transaction.
Anybody have this experience?
Any chance that HUCA would work, if they're not able to see availability on their system?
