If you're a high-tier JetBlue Mosaic traveler, your ability to use upgrade certificates is now a bit easier. As first noted by user lowkeyflyer on FlyerTalk (who shared a screenshot of an email sent from JetBlue), you can now see online availability when logged in to an eligible TrueBlue account.

As a Mosaic 3 member (courtesy of a 2023 status match following Delta Air Lines' major elite status changes), I was thrilled to see this development, as it allowed me to lock in my plans to use some of these certificates for a trip later this year.

Here's why this will be a major time-saver for members looking to book a comfortable flight in JetBlue's Mint business class.

As a quick refresher, JetBlue first launched Mint upgrade certificates in 2022 as part of its limited-time Mosaic+ status. These were then codified in the carrier's May 2023 overhaul of the TrueBlue program. Once you reach Mosaic 3, you receive four of these certificates, and you get another two when you reach Mosaic 4. These allow you to confirm an upgrade from economy to Mint on eligible flights (excluding basic economy tickets).

As of Jan. 4, you could confirm these upgrades immediately; however, at the same time, JetBlue introduced dynamic pricing — requiring anywhere from one to four certificates on a one-way flight. The only way to check inventory was to call customer service or book a refundable ticket.

Not anymore.

Now, when you're logged in as a Mosaic 3 or 4 member, you should be able to see the number of Move to Mint certificates required to upgrade an eligible flight. Simply search for your desired itinerary, and click on the economy fare bucket. This should load a message with the required number of certificates, like this example with a flight from New York's John F. Kennedy International Airport (JFK) to Los Angeles International Airport (LAX) over the holidays.

This particular flight would require three certificates to confirm a set in JetBlue Mint. However, just a week and a half later, the exact same flight can be upgraded with just a single certificate — even though the difference between the two classes is much larger.

This same view appears whether you're looking at paid tickets or award tickets, as flights booked with TrueBlue points are eligible for upgrades.

Note that this appears to only be available to accounts with at least Mosaic 3 status; the exact same flight didn't show availability when I logged in to my wife's account (she has no status).

Nothing has changed with the process of using a Move to Mint upgrade certificate. While you can't confirm these during the booking process, you can do so immediately afterward — as long as you have enough certificates in your
