Hmmm well I have yet another T3-T5 J-F connection today. Success with BA on these vehicle connections (Jag or not) is running at a round 0% at the moment. It’s been the bus every time, including a missed connection and a €600 EU261 over the last 2 years. Will see if BA finally finds my name on their list.. I even overheard a couple from MAN behind me on arrival at LHR getting a Jag last week - I saw it as we came to stand and I kinda hoped it had been for me but no..
