Jetblue as well as other airlines will give you a credit if the price of a already purchased ticket goes down if you ask for it. It gets annoying to have to constantly check to see if it went down in price especially if you have more then one flight to keep checking on. Is there any site that will alert me when a specific flight has gone down in price? Meaning - I will type in my flight date/number/destination etc and the price I paid.
