Once a Free Perk, Many Airlines Now Charge for Advanced Seat Selection

A recent Airfarewatchdog poll revealed that after checked bag fees, the most hated airline fee is the one extracted for advanced seat selection. This used to be entirely free, but no more. Say you log on to JetBlue's website to book a flight. You choose one, you select a seat you like -- paying $10 or more per leg for more room up front or in an exit row. Bang. You're done. Now try doing the same on -- what, you want an exit row? You want to sit up front? Better have your SkyMiles number handy. Got none? Back of the bus, sir. Let's say you're surfing the site of Denver-based low-fare flyer Frontier. Here, you book the lowest fare available -- clever you! -- but alas, there will be no getting anywhere near a seating plan, let alone selecting any of your favorite aisle seats up front. Not at least until 24 hours before takeoff -- and then, let's hope that all that's left isn't the dreaded middle seat. Still, things could be worse. How so? More on the wonderful world of advanced seat selection on Airfarewatchdog.
