Do the change fees apply on TED as they do on a standard UA itinerary? Even as a very loyal 1-K, I'd have a hard time choosing TED, purely based on the fact that WN allows last minute changes with no penalty other than an increase in fare. If I'm absolutely sure I'm going, I'll book UA. If there's a slight chance of a change and I can't book a full fare, I won't risk the change fee, and will book WN.
