Get Airfare Refunds from Yapta Premium Service

Remember Yapta, the site that helps you get a refund on airfare if the rate drops after you buy your tickets? My only real complaint with the service is that you have to call the airline yourself to get the refund -- a time-consuming and potentially aggravating process. Now Yapta can handle this chore for you as part of its new Premium Service. In a nutshell, they call the airline and lock down your refund.

This option is available Monday through Friday from 8 a.m. till midnight (ET). It costs $15, which is not a bad deal if you stand to pocket, say, $75 or more from your refund. To use the service, just click the Voucher link on any refund-eligible flight you're tracking, then follow the prompts from there.

What do you think? Is $15 a reasonable price? Have you ever used Yapta to get an airfare refund? If so, how was it dealing with the airline?
