I used them last February at PO-FQ. For a 5:00pm flight, they wanted to pick us up at 1:25pm! No way! I asked them for the next pickup, it was 1:55. I said OK. They said they would not guarantee our arrival on time at the airport. Even though the bus was a little late, it was raining, and we had to stop for pickups at OKW, we were at the airport by 3:00.
