Depending on the location of your destination airport, you might be planning on taking a local public bus to get to your airport after your arrival. You'll definitely save some money, and it might give you a chance to chat up a local sitting next to you.
But in some cities, the buses will not let you on as a passenger if you have too much luggage. A bag or two will likely be fine especially if the bus isn't busy. If you are traveling with 2 or 3 large suitcases, don't be shocked if you are denied access to the bus.
Don't make a fuss if it happens. They have these rules for a reason. Just accept it, and go flag a taxi.
