Noticing in the last couple of days that operators based at Stansted - Ryanair, Easy, Jet 2 all seem to be rolling along in and out pretty much as scheduled, maybe a couple of late evening arrivals delayed by an hour or so, but that is true of normal times. BA at Heathrow has multiple cancellations, longer delays, etc, that have made the press. The flight information is one thing, but after arrival further accounts of lengthy holds for gates, non-delivery of any baggage from the flight at all, etc.
Whatever is it that BA have allowed to happen that does not afflict these other London-based operators ? I did see a (non-aviation) source writing about their staff who were "off with Covid" that it did seem the "usual suspects" were well represented there among them. Is this a BA experience ?
