Total Jetblue rookie here and boy do I need your help. Started looking at Jetblue for 2 tickets from LAS to BOS on a direct flight next June. Trying to navigate their website and options has my head spinning. I want to book fully refundable tickets, that can be refunded to my original form of payment should my plans change, that I will upgrade to Even More Space. We will both have a carry on and will each be checking a bag. I thought I had figured out that tickets other than Blue Basic are refundable to the original form of payment, however when I attempted to book the Blue fare online I not only don't see any evidence that the ticket is refundable but I am offered the opportunity to make the ticket refundable for "from $68". Do I need to be looking at Blue Extra to get what I'm looking for? Thanks for any guidance you can provide.
