One way to fly is by taking a COACH, which is a five-letter word. This is the most economical option, as it is usually the cheapest form of air travel. Another option is to fly SOLO, which is a four-letter word. This is more expensive than flying COACH, but it allows for more privacy and flexibility. A third option is to fly STANDBY, which is a seven-letter word. This is when you purchase a ticket at the last minute and wait in line for any available seats on the plane. Finally, you can fly economy class, which is a twelve-letter word. This is the most affordable option for those who want to fly in comfort without breaking the bank.
