Just got on, logged in, and zoned out on some TV sit calm. Flight was easy Miami airport is something else!!! what a mess and now that I think of it, the luggage desk staff was super slow, I began to get irritated over paper running out, TSA was at the the end of the desk and the agent was assuring us we would get on flight, we arrived early, just didn't find the Alaska desk due to miss information. We walked that airport back and forth 3times. Language barriers were part of that fiasco and searching for American Airlines didn't help. (rolling my eyes)
