everything with alaska airlines was good. good customer service all the way around. check in with our return flight back with frontier...the animals on the commercials may be funny and friendly but people at the check in counter...look out! everything else on frontier was pretty good though - especially the extra leg room. our <2 year old had enough room to stand, move around a bit and play.
