Hi

I hope everyone is well.

I have quick question for all you Avios Experts out there.

On an Itin LHR-BOM-AMD-BOM-LHR, I have the LHR-BOM and BOM-LHR sectors in T class (WT+) can I use Avios to upgrade to J (subj to avail) on those sectors alone.

Also the entire trip is on one PNR purchased through expedia as BAEC wanted to charge me circa £3k for the same itin + 25k miles

Regards
Dr P
