+: No hidden fees. -: could use a couple of minor UX features.
I liked that there weren't any hidden last-minute booking fees, everything was relatively straight-up, it would be nice if there was an integrated add-on option for nearby hotel parking (affordable parking would be especially nice) it would also be nice to get the email confirmation codes resent 24 hours before each flight so I didn't have to dig through previous emails and guess which code goes to which flight. Other than that everything was pretty painless and easy to use.
