The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

I had a very disappointing experience traveling with Copa Airlines. When I arrived at the airport in Córdoba for my flight to Bradley International Airport, I was charged an additional $590 because I was told that certain taxes and fees had not been paid. However, my reservation and documentation clearly indicated that all applicable taxes and fees had already been paid. I was therefore forced to pay an additional amount that I believe I should not have been charged. What makes the situation even more concerning is that I was initially told I had to pay $890. Then, the amount was increased to $1,800, and eventually, after discussing the matter, I ended up paying $590. I consider this amount excessive and, more importantly, unjustified, since these charges had already been paid and nowhere in the terms of my reservation or contract does it state that these taxes or fees were outstanding. I am extremely dissatisfied with the way this situation was handled and with being required to pay an additional charge without a clear and consistent explanation.

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Boarding was conducted in a confusing manner as no boarding group was displayed on my boarding pass and group calls were inaudible. Flight was delayed due to oil issues and loading issues. Had to wait almost 45 minutes for bags at baggage claim.

Smooth, and met expectations.
