I had to take a flight at the very last minute and went out to the airport (Dublin) to book the soonest one to London. There was one going in about 40 mins time and the airline told me they could get me on but they only had business class available. As I needed the flight I said yes. When I boarded the plane there were only 2 others in business class and only 14 on the plane overall. Is this normal practice for last minute flights...I had no choice (for personal reasons) but to take it but I do feel a bit hard done by
