Carol.....we just went through Miami. They do have kiosks where you can print out boarding passes if needed (and even check luggage if you have any). There are numerous lines at the American counter so it can be confusing which you need to get in. We always ask as soon as we get to the American counter and they are pretty good at directing you into the correct line. You can now do Verifly for your trip to St. Maarten. I did and when I got to the counter I told the lady I had Verifly approvals on my phone and asked if that would expedite the process. She said definitely and looked at both approvals. I will say we got boarding passes and were on our way much quicker than most others. And that included checking two bags.
