To be fair, I have met some good employees as well. However the proportion of rude employees is far higher than in any other airline I've ever met. The other thing with AC is the awful employees have a much larger footprint than other airlines. The web support, the 800 number, aeroplan, the check in attendants, the gate staff (ESPECIALLY THE GATE STAFF), the crew and finally the customer complaint email all have a healthy portion of people who simply are not happy at anything they do on the clock.
Its an company culture that permeates every corner of the airline. Couple that with management that needs to be combative with these people and trying to turn a profit in this sector is bad news.
I'm probably spoiled. Because of my job I go to Europe 3 times a year and fly Virgin to London or Lufthansa to Frankfurt, I go to Guam once a year and fly Asian airlines, I go to Japan once a year and fly various Asian airlines, I go to Florida 6 times a year and fly Southwest and then...................I go to Winnipeg, Edmonton and Victoria each 3 times a year and I'm stuck on this ridiculous airline.
