Great flight attendant

Disappointed in the seating...seemed to break up couples travelling together....Will continue to buy these seats but will be more wary of the available seats next time.

The flight attendants and captain were very friendly and gave quality service. They always had a gentle smile on their faces. The flight attendant let me have one extra cup of water without being made to feel like an annoyance. The captain 👨‍✈️ made us all feel welcomed, appreciated, and safe! There was some turbulence. All crew members made us feel calm especially the captain with his calm & confident voice.

This connection to Panama from Denver is too tight. Last year the plane pulled out as about 15 people from connecting flights literally ran to the gate - we have to de-ice in Denver. This year the Denver flight landed early but I still needed to run to get to the gate - I'm 60 and it's a bit too far to make in such a tight window.
