Unprofessional? How about UNSAFE if they were REALLY taxing in with newspapers covering the windows. I doubt it happened, no one is THAT stupid.
I call BS. If you were that upset, you would have taken your bags with you. You would have posted a flight number, date, time and tail number. It's done several times on FI.com...when it REALLY happens.
Just because others are classless D-Bags, dosent mean it didnt happen. I respect Tristar for bringing it up and not having the FI 12 year old mentality of posting identifying info.
