My sister is going to get married on May Day. She wants me to attend the wedding. I work in other places, so it's inconvenient to go back. Unexpectedly, my sister booked me a round-trip ticket.

Sister is willing to book a plane ticket for you to attend her wedding, which shows that you are very important in her heart, and she doesn't want you to be absent on the important day of her life. It doesn't matter if you haven't been on a plane. You will receive the ticket information, and you can call the consultation number to ask. After arriving at the airport two hours in advance, you can also consult the ground staff at the scene.
