These bag fees apply to online purchases before check-in. Higher fees apply at the airport.

"I love Alaska Airlines!"
Flight from Miami to Seattle
Airline: Alaska
RT/OW: oneway
Date of Flight: April 2011
Seat Class: economy
Check-in Experience
In-flight Service
Seat Comfort
I have always flown Alaska, but never really knew how good they were until I flew a different airline on the way to Miami. I'm not sure if you can ever get truly comfortable in Economy, but the flight attendants and gate attendants were friendly and wonderful. It makes the entire experience that much better. Alaska sets the standard for quality customer service all across the board. I am still bothered that if you need a meal you have to purchase it, but the meals were pretty decent. And to top it off, by the time I got to the luggage carousel, the luggage was already coming out to pick up. Yea Alaska you ROCK!
