Have a feeling I know the answer to this, but here's my story. A while ago (May of this year) booked JFK-LHR in Club. Few weeks ago decided to add VIE to trip, so I booked a separate ticket (and thus, separate PNR). My issue now -- my flight into LHR arrives at 8:20 am, and I was previously on the 14:55 LHR-VIE. BA canceled that flight just now, gave me options of rebooking on 10:20 and a much later flight that would get me in around 22:00. Neither are great, but I could do the 10:20 flight if I were on the same PNR, or could do 10:20 if BA would let me move my flight to LHR earlier. Thoughts / suggestions?
