Can you take a tennis bag on the airplane?

You should be able to bring tennis bags on most airlines, but you have to be careful about the size. Most airlines specify size limits that are a sum of the length, width and height of the bag. If your bag is 25" long, 12" high and 10" wide, that's a total of 47 inches. If the airline had a limit, this bag would have to be checked. You probably won't be able to carry on a 12 or 15 pack bag, but 6 packs should be OK. Always check with your airline and have a backup plan if they check your bag.
