I got the JetBlue Plus card several months ago and I am supposed to be entitled to a free checked bag. Does anyone know how to book the reservation online to get this benefit? I have tried several ways, of course using the Jetblue Plus card to pay, and it's really not obvious at all at what point the bag fee gets deducted, if ever. Does Barclays or JetBlue issue a credit once paid? Has anyone successfully accomplished this. If so, can you please describe the steps required such as what fare type to select, etc.. and at what point JetBlue realizes you are paying with their JetBlue Plus card.
