I'm in the Boston area and looking at flights to Costa Rica for April 2025. My current plan is to book roundtrip flights from MCO to SJO (Costa Rica) on Jet Blue. I'll deal with flights to and from MCO/BOS or PVD later, probably on SW, but for now I'm going to transfer 234,500 MRs to Jet Blue to book the 5 tickets I need. To SJO they are 22,000 Jet Blue miles each and 15,500 each for the return. But before I do, I thought I'd check and see if this seemed like the right move. I'd obviously love if Amex was doing a promo with Jet Blue since the rate currently is 250 MRs for 200 Jet Blue miles. But the ticket prices don't seem too bad to me, so I want to move on it sooner rather than later. Do I just go for it? Is there a better way?
