I need to book a flight for me and my spouse.
I am supposed to get a refund for my ticket from my workplace, but we need to pay for my spouse's ticket ourselves.
In order to get the refund, I need to submit a receipt for my own ticket, however when booking a flight online I believe I will only receive one receipt for both tickets.
I can book each of our tickets separately, but there's a few things I'm afraid of:

• The price might be higher.
• The first ticket I book might be the last ticket for that flight at that class.
• We might not get adjacent seats.

Am I right to have these concerns or am I just paranoid? Is there a way to book two flight tickets online in one purchase and get two separate receipts?
