Tomorrow our flight leaves BKK at 11:15. You should report at the airport for check-in at 9:15. You can enter from Gate 4 or 5. Check-in Row will be H/J. I will wait for you there.
Make sure to bring your passport along and your bag should have a lock!
If you need me for anything, you can contact me on my mobile. I will leave home at around 8 AM to go to the airport.
