Question for those in the know:

I have a couple of booking in ET done via OTA and currently when I try to upgrade on Manage my booking I get the message that I am not authorise to change the booking (expected).

does anybody known if this would change at OCI and/or a bag drop off?

I have in the past been able to see the upgrade prices for all my direct booking but on this occasion, as I had to return with a different airline on both bookings due to flight time availability, I had to go through the OTA route.

Thanks in advance
