tcmstr - It's a ticket United sold me on their website. UA1104 arrives from Denver at 11:32 AM and UA1549 leaves for Cozumel at 12:04 PM.
I booked it a couple months ago & didn't really focus on the layover time. I assume they think it's going to work since they booked the ticket. But when I noticed that 32 minute window, I lost a little sleep. Even if we make it, I'm wondering if the checked luggage will.
On the plus side...it's practically a non-stop flight!
I was about to call them & discuss changing it (and eating 4 change fees), but I thought I'd get some input here first. Thanks to everybody for their thoughts/experiences.
