The most common booking mistake we see, and the one telephone call that fixes it.
Somebody books a room for the fifteenth because their flight is at two in the morning on the fifteenth. Then they arrive at the desk on the evening of the fourteenth to find nothing reserved, and everybody has a bad half hour.
A room by the night runs from two in the afternoon until eleven the next morning. So if you are taking off at two in the morning on the fifteenth, the night you sleep in is the fourteenth, and we drive you to the terminal at around eleven that evening.
The simple rule: book the date you will be asleep on, not the date printed on the ticket.
We catch most of these ourselves, which is why we ask for a flight number rather than a time when you book. Reservations reads every one, and roughly one guest a day gets a telephone call that starts with a question about their ticket.
The other half of the same problem is the arrival side. A flight landing at half past eleven at night means you reach the desk at about quarter past midnight, which is already the next day. Book the night you land on, and the desk will have it right.
If any of this is unclear, send the two flight numbers and let us work it out. It takes a minute here and it saves an argument at a desk at midnight.
