I have recently finalised a booking made through BA Holidays (hotel + flight) but can't see any option to upgrade my seats for my partner and I.
Usually when I book flights with British Airways, I tend to get an option to upgrade my seating from Euro Traveller to Club Europe however I can't find this option. (These are flight only bookings).

Having worked for Virgin Atlantic previously, I know that *sometimes* our customers had an option to upgrade online if they booked through Virgin Holidays but that was often far and few between. They had to either ask VHols who would sometimes do it or wait until they get to the airport. They also used to be able to use YourBid once upon a time also.

My understanding is that a BA Holidays booking is probably treated as a travel agent booking but is it ever possible to upgrade at the airport with BA?

I've never done this before.

Also how much roughly would I be looking at paying, I know VAA had fixed pricing at the airport.

This is for a return flight. Outbound seg is LGW to AMS and the inbound seg is AMS - LCY.

Hoping to bump from Euro Traveller to Club Europe on either seg (possibly both)
