Names on Airplane tickets from pricelines

Answers to I just booked 2 tickets (for myself and my sister) from Priceline websites - they're international flights. After my tickets got confirmed, I realized that I didn't put our middle names (assumed they're optional), even though they do appear on our passports, driver's licenses and other government documents. However, since we go to school and not using our middle names - I get used to it and not filling them when I was booking my tickets. Is there a problem. I chose Delta and Vietnam Airlines as my flight agents. Thank you
