Cheap Flights from Los Angeles to Cancun from $50

Our only problem is we did not get our assigned seats until an hour before flying. I tried to purchase choosing our seats before the day of the flight and I could not. Then we could not even get our seats for the second leg of our trip until about an hour before we took off. So we departed from our first flight and had to check in at the counter when someone arrived at the desk for our first flight. This stressed me out not knowing if I was going to be able to sit with my husband.
