Who doesn't fancy seat upgrades on flights, right? If you travel frequently on Alaska Airlines, you might want to take some time to go through and understand the updates the carrier has rolled out. Alaska Airlines recently announced some big changes to its First Class upgrade policy, which will impact your flight upgrade depending on your status with the carrier. Here is a brief look at what's going to be changing this fall.

1. Free First Class Upgrades On Award Travel, Starting December 5, 2016

With the Mileage Plan™ program, if you have elite status, the program offers free unlimited upgrades to First Class. Here are the fares you need to book.

Flights booked before December 5, 2016

MVP® members: Y, S, or B fares
MVP® Gold members: Y, S, B, M, or H fares
MVP® Gold 75K members: Y, S, B, M, or H fares

Flights booked on or after December 5, 2016

MVP® members: Y, S, or Z* fares
MVP® Gold members : Y, S, B, M, or Z* fares
MVP® Gold 75K members: Y, S, B, M, H or Z* fares

Z* = refundable Main Cabin awards. All tickets booked in Z class will become upgradeable, starting December 5 2016, regardless of the date booked.

2. Changing The Upgrade Window For Non-Refundable And Discounted Fares

If you buy a discounted fare that doesn't qualify for immediate upgrade to First Class, you will be put on the upgrade waitlist at the upgrade window, based on your status level. Just to emphasize, upgrades will be processed by elite status level first followed by the time of booking.

Main cabin rewards (W or N fares) that are non-refundable will be upgradeable starting December 5, 2016, regardless of the date you book the flight.

Upgrade Windows

MVP members: 48 hours prior to departure
MVP Gold members: 72 hours prior to departure
MVP Gold 75K members: 120 hours prior to departure

3. Free Upgrades To Premium Class, Starting January 2017

Starting in January next year, certain fares will be eligible for an immediate upgrade to Premium Class - if space is available and if you enjoy Mileage Plan™ elite status. Premium Class boasts extra 4 inches of legroom, free snacks and drinks, as well as early boarding. Here is a list of qualifying fares that will get you that immediate upgrade that you've been wishing for.

MVP® members: Y, Z*, S, or B fares
MVP® Gold members: Y, Z*, S, B, M, H, Q, L, V N, or K fares
MVP® Gold 75K members: All fares

If Premium Seats aren't available for the flight, you will be put on the upgrade waitlist.
