Boarded plane and then delayed 1.5 hours while on the plane

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

We were given vouchers we couldn’t use with a 5.5 hour delay

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

Great flights. 90 minute departure delay for maintenance issues, not a great start but, afer that very good. Didn't pay extra for seats and lucked into a window and an aisle seat. Price was excellent at the super low economy level.

Just a little improvement on food but everything is excellent

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

They lost my checked in luggage, why do I pay for my cargo not arriving at the same destination as me?

Poor planning meant the plane was delayed an hour, then a thunder storm started and the ground staff couldn't work. Eventual arrival in Santiago was 3 hours late resulting in missed connections and the need to buy new tickets.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

Terrible all around. Flight was late and airplane was very uncomfortable. The crew were unhelpful and hid in the back. Did zero work. No entertainment.

The pork noodles were disgusting. The tuna sandwich had hardly any tuna and the bread was stale. A salad would have been better. An apple or a muffin.
