Original routing was DUB-LHR-DFW-LAS-PHX // SAN-PHX-DFW-LHR-DUB. Started in DUB Monday 28 and did TATL on Tuesday 29. Return is on Sep 9 arriving in LHR and onto DUB on the 10th. Pretty sure fare basis was INX1C1S4 with over 180 days advance purchase. Ticketing date was around Jan 29. I think the issue here will be finding anything in I class on any routing.
Thanks again for checking this!
