Aeromar has the most restrictions and the most lenghty boarding process,there will allways be something to make your boarding experience a nightmare,I recommend to stick to the professional airlines like Aeroméxico,in a world of conecting flights this is surely the worst option,they will allways be quick to remind you you must donate 2 hrs of your time to board an Aeromar flight, Aeroméxico 30 min flat not worth your money
