Judging by the report on BBC news 24 about T5 at Heathrow being closed, and BA handing out letter to prospective passengers telling them that BA can't arrange hotel accomodation due to the numbers of passengers involved & advising them to leave the airport , it seems not.
Not a very good advert for BA's customer service planning if this is the case.
Just hope that my two colleagues who were heading back home from Houston via Schipol yeterday have made it home. KLM seem to have done a good job in arranging several options for them to either stay over or try to get home. Haven't heard today, but they were last heard of, waiting on a train to Brussels to either pick up a flight to Edinburgh or Glasgow, or to head back via Eurostar, or if all else failed, with hotel rooms booked in Brussels for them - all at KLM's expense. All the more surprising, seeing as it wasn't a particularly pricey ticket they were flying on.
