Best tactics for booking a large number of seats on a flight?
What are the best tactics for booking a large number of seats on a flight, particularly when it's within a few days of departure?
I know that when you book seats separately, i.e. one after another, there's a risk that the earlier purchases will drive up the prices for the later purchases, especially if there are a limited number of seats remaining on the flight.
Can this be avoided by purchasing all the seats together at the same time, i.e. as part of the same order?
