I think it's unfair that you have to pay extra to bring 1 small suitcase on an international trip. What happened to the area of the plane that used to house people's luggage as part of their normal airfare? I am very pleased with the Delta/Aeromexico partnership. There still seems to be a gracious demeanour that is most welcome in this day and age of efficient bad manners!!
