I would think that FTers cost more money or earn less for UA than the average non-FT flyer. Many FTers are good at finding the cheapest fares, remembering their MP#, maximizing mileage, getting bump vouchers, utilizing promotions, getting compensation, finding loopholes, etc. Most UA flyers are not that informed.

We would save money and increase revenue for UA if they listened to our advice for fixing their crappy Website. I'm sure there would be more bookings online and less people calling phone agents to do simple things that should be de rigeur for any decent airline site.
