Being stopped at every connection for screening. No communication about why. Nearly missing the connection due to the screenings. Being held in holding because it was being confirmed that my bag would make it on my next flight and then once confirmed it never made it anyways!!! Unprofessional and poorly executed all the way through.

I was traveling with my 11 month old daughter and everyone went out of their way to assist us and I didn't feel like a burden to them. When she was sleeping on my lap during the flight they even brought me my meal in portions so I didn't have a huge tray to balance over my baby.

Everything was great

had to take another flight, ticket agent was able to change me to a different flight on JAL. however, JAL could not access the ticket info and ticket agent would not take my payment. result was missing that flight, ticket manager told me it's my fault and tough luck no refund. American airlines told me the same, ended up losing my money for the ticket purchase. i booked another new flight with another airline direct. worst experience in my life using kayak.

Oh the crew was very pretty. They spent more time on themselves their hair their make up and on their phones than they did the entire first class. Check our flights and miles. We fly AA ALOT for ourselves and other. WCB4350 Shipman. We don’t complain ever. But when you spend what we do and only just get your first drink with your dinner in the air is utterly ridiculous. Never got a clean up or a second drink. Had to interrupt the glam squad from their phones and make up bringing them our dirty glasses and trash asking for a second drink. Not impressed with this crew at all! Normally AA IS TOP KNOTCH. So it sets the standard that we’ve been accustomed to however complete and total letdown on this flight

Flight back was OK but flight to Orlando was not. Travelling with s 94 yr old man in a wheelchair. Everything at Pearson is not conduscent to travel with a handicapped person. Poor layout, poor assistance, non caring people, long distances,, and final straw was air canada started boarding without calling for handicapped first. We had to stop them and then fight our way up the aisle with people all in the way. Terrible, just lousey. 3 and a half hours before flight we arrived and didn't even have a chance to get some lunch before flight. I give Toronto and air Canada the worst possible rating of any airport or airline I've ever dealt with. John O"Hearn

Onboard attendants were pleasant

No apology for lateness, flight boarded late, took off 40 min late, arrived 35 minutes late but we sat at gate waiting for someone to open it ?!, then another 15 min before bags started to unload Ridiculous but indicative of airlines You are not their valued guest or even their customer, you are a problem that needs to be solved and are consequently met with preloaded annoyance and a readiness to dismiss, placate at the best of times but definitely not please, impress, sympathize or satisfy. There is no evidence that it's even in their lexicon- not a part of their recruitment or selection process or training, ever! They're main focus and only positivity is saved for themselves. There may be a long line of concerned and anxious travelers but their priority is getting coffees for the battle ahead! They break their focused indifference only for each other and enthusiastically leave their post to satisfy each other's needs and attention. This has got to change! Why do we put up with such awful service for which we are the paying customer? Why are we, their customers, not valued? This airline makes record profits, provides less, charges for everything and increasingly delivers bad service, sometimes offensively bad! It doesn't cost more to hire a customer centric pleasant person, or incorporate guest experience into training or at the very least be friendly and smile! What if an airline just did that?! They'd differentiate themselves and develop a positive customer centered culture. Don't we deserve that, at the very least?!
