Is the end of scrambling for overhead bin space near?

Boeing revealed new overhead bins on its Boeing 737s that will give passengers almost 50 percent more space for carry-on luggage.

Alaska Airlines is one of the first major airlines outfitted with Boeing's bigger and wider bins, it dubbed Space Bins, which will fit six bags instead of four.

In order to do that, it’s sacrificing about 2 inches of head space, says Boeing.

But the move could mean savings for passengers who spent $3.5 billion last year on fees to check their bags--and are trying to find ways around check bag fees, which average around $25 per bag.

 On Alaska’s 737-800, the expanded bin space will increase the number of bags that can fit overhead from 118 to 178 — a difference of 60 more standard sized bags.

"Alaska is relentlessly focused on making the travel experience better," Sangita Woerner, Alaska Airlines vice president of marketing said in a release. "We've been on a mission to improve our cabin experience for several years and Space Bins are part of a $150 million investment we've made to make flying more comfortable and enjoyable.”

Within two years, nearly half of Alaska Airlines' fleet will be fitted with the larger bins, the airline said.   Delta will also have Space Bin 737s in early 2016 and United has also committed to the bins.

But that doesn't mean you can bring on a bigger bag--- the size limitations for carry-ons on Alaska will stay in place.
