Just before departure and during the flight, it is very good to recite the names of the ten directions' buddhas. If you keep on reciting the names, in whichever direction you are flying, if you recite that Buddha’s names and pay one-pointed attention to this, not only will you be free from danger, but your wishes will be fulfilled. So not only is this for safe travel, but for the successful fulfillment of whatever goals you had for going in that direction.

It is very good to pray not just for your own safety, but on behalf of all the people in the airplane—all 300 passengers and crew, or however many people there are—for them all to have a safe journey. Not only that, but you can pray that whoever this airplane carries may always be safe. It’s very good to pray like that.
