My sister flew them in January. We have done No-Frills several times out of Buffalo, AirTran and Southwest. And she was very disapointed. You had to pay extra for any beverage except water, the flight had a 2 hour delay, the bathrooms had no running water so the flight attendants were giving out hand sanitizer.
She said never again.
Also the price. It was almost $500. She could have gone Southwest for half that but needed to come in to Toronto.
