I’m planning on taking a solo trip from the US to Mexico City in January. I’ve never flown internationally; in fact I’ve never even used my passport. When looking at flights, I want to make sure I have enough time between transfers in case there are hang-ups, I’m just not sure what to expect. When flying in the past, I usually get to the airport with less than an hour before my flight (it’s a small airport and I’ve never had issues with security) however I feel like that will be different flying to another country. My first flight would be to Seattle and then a layover followed by a direct flight to Mexico City. What kind of documents/security should I expect going in? Will I fill out the documents at my small airport and then be fine until my return flight? I’m expecting to get to the airport earlier than I typically do, but how early is necessary? Thanks in advance for the insight!
