Hi all, long time lurker and first post here.

Planning to take advantage of the recent ex-DUB sale fares to the US via LHR coupled with a UuA from CW to First on the transatlantic. Having a look at the wiki I understand to upgrade I'll need to book the TATL on a BA code. However can anyone confirm whether when booking through BA would I still get the 210 TP domestic first rates for any >2000 mile sector as long as I get the agent to book it under the AA number?

Thanks for the help!
