I just flew to and from Charlotte, NC on business. I flew down by Air Canada and flew back by US Airways (it was 1.5 hours earlier than the AC flight so I picked it). I was shocked to be told by fellow passengers, in the hotel shuttle on the way back to the airport, that I would be charged $4 or $5 for a pop on US Airways. I have NEVER paid for a non-alcoholic beverage when I've flown...but I hadn't ever flow US Airways before.
On my way down by AC, there were some problems...we were delayed because of mechanical problems but I'd rather they fix the plane than not...y'know. The flight down was uneventful and I got an entire can of tomato juice...for FREE.
In the hotel shuttle, the guy said that at the airport he flew out of, the US Airways gate agent was making jokes (at the company's expense) about what they had to pay for. He was warning them to buy stuff before they flew. He said, "This is what's free. That button above your seat that you push for light, that's free. The washroom is free...for now."
I've had bad experiences with United and vowed NEVER to use them again...well, I used them again...but admittingly, only when I found out it was a code share and it was being operated as an AC flight.
Probably, and I write this with only my opinion to base it on, is that most people who complain about AC have flown a lot of flights on AC and a few flights on other airlines. So...exaggering a bit, if you've flown 100 times on AC and 20 times on WJ, chances are you will be having more incidents on AC than WJ because of the number of times you've flown with them. The majority of my flights have been with AC. I've flown West Jet on two trips. One of my WJ trips was delayed at Pearson. A few of my AC trips have been delayed.
I like AC. I like WJ. I'm so so about US Airways although it was only their beverage policy I hated and I've only flown them once so... who knows.
I'm considering Porter Airlines right now for a business trip to NYC instead of AC or AA... and it's a hard choice because I do like AC but Porter's got a deal on right now that's about $50 cheaper than AC. I think we're incredibly lucky to have reliable airlines that are not going belly up.
