Cheaper Airplane Tickets when Shopping for Multiple Passengers

Reading my February 2014 (somehow I got it over a month ago) copy of Kiplinger's Personal Finance I came across a helpful tip from Rick Seaney, CEO of FareCompare and airfare shopping guru. He says that airline reservations systems charge everyone in your party the same higher price even if there are a few lower-priced seats available. Given this you'll save money if you shop for airline tickets one passenger at a time when booking multiple people. Mr. Seaney mentions saving more than $1,000 using this method booking airfare to London.

The only exception to this I can think of is when booking a complimentary or discounted companion fare that some credit cards and airline rewards programs offer.

Let me know if you have any good tips for more affordable flying below.
