Just completed my fourth CO trip in 3 weeks. As a Gold Elite, I've either sat in exit rows or, like today, been upgraded to First (today with my wife). Airlines have massive hard costs. These boards are chock-full are critiques about the "hard" product - are the seats comfortable, do the Business Class seats go to 180 degrees and are they flat or angled. Lots of money goes into these things. Today's "rant" is about none of that - it is about the flight attendants. On all of the flights, not once did I see anything even approaching a smile. More amazing, whenever I or another passenger did receive something like a soft drink and said "thank you", not ONCE did I ever hear the attendant say, "you're welcome"! Forget the Ritz Carlton standard, "my pleasure!" Is it so hard? To see this ongoingly makes me feel that it is something that CO is more than willing to allow and live with. But today was the worst. As I said, we were upgraded to the first row of First Class on a flight from Nassau, Bahamas to Newark. I could not believe that even in First Class, the attendants could be so surly but the main one most certainly was. Nary a smile, the barest and most basic interaction that she could get away with was good enough. It was a 2.5 hour flight. After the first hour, their work was done. At that point, three flight attendants proceeded to talkin the galley at the loudest of levels for almost the entire 90 minutes. Not only did they not once check out if everything was OK, the volume of their conversation was only matched by the inappropriate topics they discussed. It ranged from how the job sucked, which other attendants they couldn't stand, who is a slut, children "sext-ing" and discussing teenage sexuality in general, etc. There was a young woman in the first row on the other side of the aisle and altho I don't consider myself a "fuddy-duddy", I as embarrassed. Oh and by the way, they seemed to have no trouble smiling at each other - only when dealing with passengers. I can tell you that altho I tried to nap, the volume made it simply impossible. I can think of no other airline where I have observed such behavior. More astonishing, not one of them thought it important to check out the passengers before landing to assure seat belts were fastened and whatever else they do. Everyone says that travel is harder and harder and is no longer something to look forward to but rather to be tolerated. That has not been my experience on BA, Swiss, AF, etc. But if CO or United simply decided that this stuff matters and insisted on training and behavior standards, it could change the mood significantly, and it would, basically, be free for them! Okay - rant over. I just wish I felt better!
