Can you purchase an airline ticket on Priceline.com for someone other than the card holder

Have or I should say had a job interview in another state and the prospective employer said he'd buy my airline ticket. 3 weeks go by and tomorrow I'm scheduled to fly out... when I asked for the intenerary, I was told Priceline won't allow him to buy me a ticket because my name doesn't match what is on his card...that I should buy my own ticket...and he'd reimburse me... 3 weeks ago the ticket was $350... now, last minute it is $1200. should I believe him and trust the repayment?
