well IIRC there were regular and numerous threads on this board ".....ing" about how Lufthansa can provide a premium ground transport service at FRA and BA just herd its premium passengers into busses.....So given the high frequency of remote stands at T3 until fairly recently BA listened and acted. And very welcome a development it was (at the time). perhaps less relevant today now T3 is gate departures and after October when T5/T3 rebalancing happens again.
