About Alaska Airlines

Alaska Airlines is a legacy U.S. carrier — think real seats, checked bag fees, and a frequent flyer program worth actually caring about. It's not trying to be a budget airline, and it's not pretending to be a global mega-carrier either. Its identity is firmly rooted in the West Coast, with SEA as its beating heart and 109 routes fanning out from Seattle alone. Across its whole network, Alaska connects 142 airports over 766 non-stop routes, stretching a combined 1,746,520 km. That's a serious footprint for a carrier most East Coasters underestimate.

Why fly Alaska Airlines?

Honestly? Alaska punches above its weight on loyalty perks. The Mileage Plan program has a reputation for being one of the more generous ones out there — frequent flyers genuinely accumulate miles fast enough to feel the reward. The West Coast coverage is hard to beat, especially if you're routing through PDX or SAN. And that SEA-FCO route? Seattle to Rome non-stop at 9,131 km is legitimately impressive — it tells you this isn't just a regional hop airline anymore. Service tends to feel less transactional than the ultra-low-cost carriers, and if you're flying up to ANC or around the Pacific Northwest regularly, Alaska's schedule depth makes it the obvious call.

Tips for booking Alaska Airlines

Book early on Mexico routes — Alaska runs 32 of them and they fill up fast, especially out of SAN in winter. If you're connecting through SEA, give yourself more than the minimum — it's a big airport and Alaska's gates are spread out. Check your fare class carefully before assuming you're earning full miles; cheaper fares often earn at a reduced rate. Alaska flies to Japan (3 routes) which surprises a lot of people — worth checking before defaulting to a bigger carrier. One thing first-timers miss: their baggage fees apply per segment, so factor that in if you're connecting.
