Dressed for flying

I don´t know if it´s a gay thing or not but I always dress up for flying. I guess it´s an old habit from the old days when I travelled coach and desperately was hoping for an upgrade. These days even people in business and first class dress for comfort and it seriously offends me. I know it´s not comfortable to sleep in a suit and not all airlines provide pyjamas unless you are in first but seriously pack your comfort wear and change after dinner. It is rather off putting to sit and drink your champagne and eat a nice lunch or dinner when your fellow passengers are dressed like it´s "fredagsmys" (swedish ritual meaning eating potato chips in your comfort wear in front of the tv on a fridays) The attitude seems to be "I paid for it so I can dress however I want" Frankly the whole idea of comfort wear is alien to me.
Most people in a premium cabin travel for business purposes, and they have drsscodes in the office, why shouldn´t that apply when you travel as well ???
We can not always blame the airlines for taking the glamour out of premium travel, as a passenger you have to make an effort as well...............How much fun can it be for a cabin attndant to perform caviar service to people in sneakers and sweat pants ???

I urge al airlines to implement a dress code in premium cabins, not only for travelling crew but for all passengers.
