<p>Half a year ago, the price was dropped after I had bought the ticket. I called the airline company, and they refunded me the difference in the form of voucher. The value of the voucher is $240.</p>
<p>If I book a ticket for $200 and pay for it with the voucher, what the airline company (AA) will do about the the remaining $40? Will I lose the $40?</p>
<p>Also, it seems I can not use the voucher online at aa.com. I need to pay it using the voucher at the ticket counter at the airport.</p>
<p>I will appreciate it if anybody could share with me his/her experience.</p>
<p>Go to AA.com, do a search for ‘voucher’ (top right of their website) then click the second returned link for FAQs on eVouchers. </p>
<p>If that’s what you have they say you can use it online and if you have a remaining balance you can use that on a future flight. You can’t get it back in cash though.</p>
<p>I found out that eVoucher and Transportation Voucher appear to be different. For example, for eVoucher, you get both some voucher number and PIN number. But for the paper-based Transportation Voucher, you do not have the PIN number.</p>
