Getting from place to place in general can be difficult for the one-armed. But thanks to certain events, traveling in certain venues has been made more difficult for everyone. Honestly, if you can avoid traveling until you heal, you would probably avoid a lot of trouble.
If not, there are certain things to keep in mind. First of all, if you are going on a short trip, your best bet is to pack as light as possible, and go with a carry-on with a shoulder strap. Stay away from roller bags; you lose your good arm and will have to let go of it to do anything. If you need a roller bag, you would be best to check it so that you're not dragging it with you through the whole airport. With any carry-on that can't fit under your seat (kudos if you can pack
that light), you're going to need help getting it into the overhead compartment. This is one of those times that you'll have to ask for help from someone. People tend to be most helpful while boarding and deboarding the plane, because while boarding they haven't gotten annoyed by their fellow travelers and while deboarding, they're so happy to be leaving the plane that they momentarily forget about any annoyance. Anything that you are going to need during the flight should be taken with you to the seat at this point; good luck getting any help during the flight.
Do make sure that your carry-on is the right size. Airports, especially those that charge for checked bags, are going to be a lot more picky about what types of carry-ons they will let people have.
For longer trips, where you must pack large bags (or more than one), you might want to consider a baggage pickup service. A few services exist. Some ask you to categorize your bag as small, medium, large, etc. and then charge a flat rate for different delivery times, such as
Luggage Forward, while others charge per pound based on delivery time, such as
Luggage Free. I was able to find a few services by just googling "Home baggage pickup". This might be the way to go if you have a lot of luggage and are not likely to have help with it at your destination airport. It will probably not be cheap, especially if you want them to pick up your bag shortly before you plan on leaving for the airport. Basically, in that case you're doing overnight delivery of a large item. You do the math.
There are also shuttle services from hotels and certain locations to the airport. If you don't travel during a peak time, your driver may take pity on you and give you a hand with your bags. But don't count on it during busy times. In fact, if you're banking on altruism (and nothing else), avoid busy travel times.
Whatever you do, don't wait until the last minute to figure out how to handle bags or you're liable to encounter problems and expensive services.
Your next issue is with security. All the removing of shoes and clothing items can be difficult for people like us. If your airport uses the coded lines, you might consider using Family & Special Needs, or if you're feeling adventurous, Casual. STAY AWAY FROM EXPERT! Minimize the number of things you have to mess with when you reach security. If you have a coat or hat, take it off when you get into the airport and cram it into your bag. Wear shoes that are easy to remove. When it's your turn at security, place your items on the belt and then step back to do any clothing removal. This will keep annoyed passengers from commenting on your slowness. Step back in line when you're ready. You should be able to zip right through the rest of security.
These are the major issues at the airport. As for minor issues: avoid buying anything inside the airport. I'm bad about buying a book or a magazine to read on the plane. If you must have something to read or do, get it before going to the airport and pack it in your carry-on. If you're like me, you'd have trouble getting your purchased item into your bag with
two hands. Just stay away from news-stands, bookstores, candy shops - whatever your craving is. Get to your gate, have a seat, and relax. You've made it pretty far.
Hopefully things will be easier for you when you get to your destination. At least you won't have to mess with security again.
