Congratulations. I used to work on the Sun.
You will not be confirmed as hired until you send successful results from your pre-employment physical.
The results of your drug test are also critical.
You will only get Business Class if you pay for it. Otherwise it is economy class.
Only senior Officers get Business Class tickets.
The Agent should meet you at the airport. You will receive contact information with your flight details.
If necessary, they will arrange a hotel for you.
