Airport pickup

My parents and my niece are on their way to Spain now and will arrive here this afternoon. My tiny little car, though, only has four seats and isn't large enough to pick up three people and all their luggage. Fortunately, I can borrow a larger car for the airport run today, so that I don't need to spend two hours doing a double trip. My brother arrives on Monday, and my own car will be fine for picking up just one person.
