Hi and best wishes on your upcoming travel! As others have shared, it likely depends on the airline with whom you are traveling. We have traveled Delta multiple times and JAL once for long distance flights and in all cases there has been an aisle chair on board, a small chair which allows for transfer through the airplane to get to the restrooms. In addition to understanding whether there is an aisle chair on board is understanding the degree to which staff will assist and whether there are restrooms on board large enough (or can be made large enough) to accommodate the wheelchair. As others have noted, contacting your airline and confirming the information in advance of your trip will be important. We also confirm the aisle chair is on board immediately when we are seated on the plane as another check. The chair has always been present, however staff have not always known where it is and so it has been a reminder for them as well. Wishing you the best!
