This Costa is the only 24-hour cafe at Heathrow T2. When security has not yet opened for morning flights, passengers are trapped in the departures area with Costa their only option. It's a big cafe with lots of seating, but they close nearly all sections in the early hours. The one open section was full of people camped out for hours, most not actively eating or drinking. We asked if we could sit in one of the other areas, but they said, no we must sit in that section. We pointed out that there were no seats, they repeated that we must sit in that section. They said they would call security if we sat anywhere else. No offer to move people on who were hogging the only tables. Rather than buy a drink/meal and have to eat it standing up, we decided to go hungry. read more
