What Cabin Classes Are Available on Frontier Airlines Flights to Portland?

Frontier's standard Economy cabin uses a 3x3 seat layout on both the A320neo and A321neo. Seats have a 28-inch pitch, which is tight but typical for ultra-low-cost carriers. In-flight entertainment is available through Frontier's app on your personal device. There are no complimentary meals or drinks, but you can purchase snacks and beverages onboard. Personal items (18 x 14 x 8 inches) fly free, though carry-on and checked bags cost extra.

Stretch seats are in the first few rows and exit rows of the aircraft. They offer about 36 inches of pitch, a meaningful upgrade over standard economy. These seats also recline slightly and come with priority boarding. Pricing starts around $16 to $25 depending on the route, and they're worth it on flights over 3 hours.

UpFront Plus gives you a window or aisle seat in the front of the cabin with a guaranteed empty middle seat next to you. It's Frontier's answer to travelers who want more personal space without paying for a separate cabin class. Upgrades start around $49 and include priority boarding.

New for 2026, Frontier's First Class seats occupy the first two rows in a 2x2 layout on select A321neo aircraft. The seats are wider than standard economy, built by Italian manufacturer Geven, and pre-reclined. They don't recline further or go lie-flat, so it's not comparable to legacy carrier first class. But for extra space and no middle seat at a fraction of the price, it's a solid upgrade. FRONTIER Miles Gold members and above get complimentary upgrades when available.
