Don't fall for their "cheap" fares. They more than make up for it with their rip-off baggage fees -- $50 for each small carry-on suitcase! -- which they did NOT inform us about when we booked online.
They also would not honor a bereavement policy that most reputable carriers honor. And even knowing that we had quickly booked the flights under the pressure and duress of attending a funeral, they were unwilling to make a change because we were just minutes beyond their 24-hour rule. This added 12 hours to our short-term trip.
Not only is this no way to run a business, but they add insult to injury by not even pretending to be sympathetic to any of this. And that wouldn't have cost them anything...
