Hi,

yes when booking a partner award via BAEC selecting infant throws up an errror.

I believe this bug may have been fixed by now…
I booked via the webpage as BA app is glitchy.

iif you have enough avios, booked directly via QR PC as this ensures any issues can be resolved with them directly.

I learnt this the hard way as has separate avios tickets for DOHA to Sharjah. Outbound was fine as flew first class so accessed Al safwa lounge.

on inbound my tickets did not have an e-ticket number. Most likely during the flight time changes over last few months something broke.
in the end blight avios tickets online whilst standing at the counter at Sharjah in order to get back to Doha on a later fight that evening!

luckily my 9month old was sleeping. QR Agents tried their best by as it was a BAEC booking they were blocked. They took pity and blocked the sit off next to us as we were flying back in economy.
