The days of moving up to a better, empty seat on the plane after takeoff are, for the most part, long gone.

Sure, you might find a flight attendant willing to let you move up to a seat you didn't buy, with a wink and a nod. But airlines have found ways to squeeze every ounce of money out of the plane, from checked bag fees to seat selection fees to “preferred seating,” economy seats at the front of the plane that cost more.

One United flyer realized this the hard way after taking to Twitter to complain about his recent flight, when he was told he couldn't move from his full row to a completely empty row closer to the front of the plane.

 

 

United initially responded that those empty seats were Economy Plus – closer to the front of the plane with more legroom. American Airlines also offers a similar seat called “Main Cabin Extra,” while Delta has an entirely different fare class called Comfort Plus.

And because those typically cost more than a standard economy seat, the United social media team said it “is not fair to the customers who did pay for the upgrade.” When Patel didn't buy it, United threw down the gauntlet.

 

 

As you might expect, that analogy didn't go over to well with an already aggravated United passenger.

 

 

Our Analysis

While comparing a few extra inches of legroom to a Lexus is about as far off base as it gets, the airline has a point. And so does Patel.

On the one hand, it seems to make sense to allow travelers to move to open seats after the plane doors close. Those seats can no longer be sold, and giving passengers on board a little something extra at no cost to the airline is a nice touch in the increasingly uncomfortable and hostile world of air travel. It breeds loyalty.

Unfortunately, that's not the kind of loyalty airlines want – or the kind of loyalty that makes them money.

By doling out these supposed upgrades for free, it removes any incentive for passengers to pay for them. If you know you there's a chance you can squeeze into one of these seats for free after takeoff, why pay for it?

It's one thing to move to another empty, standard economy seat. But this is clearly different. And United – and all airlines – would much rather reward frequent travelers with status with these seats – or give them to anyone willing to pay more upfront.

 

Bottom Line

Don't expect to move up to these bigger seats for free, even when they're empty. And be prepared to get trolled on Twitter if you do.
