I was surprised how clear the layout was and easy it was to get through to the payment. However, the only complaint is the hidden seat fare. It was NOT obvious. It was asked as a preference and then the price was not listed, so I also got charged for a seat. Thankfully, they were wonderful on the phone, and got the charge rebuked without any fees or need to cancel the flight. I would say this was one of my best flight booking experiences, and if they take this advice about the hidden seat fee and make it straightforward, their amazing flight prices and layout could get them very popular on the internet!
