JetBlue BlueFirst is the airline's new domestic first class, and you can book it this fall. You get two-by-two seating, five inches of recline, up to seven inches more legroom than a Main seat, and a 13.3-inch screen at every seat.

The first aircraft flies later this year. Four things JetBlue has not answered decide whether it is worth chasing, and upgrade policy is the big one.

What JetBlue's BlueFirst Cabin Includes

The seat is custom-designed and uses Tuft and Needle's T&N Flex foam. Every seat gets a 13.3-inch seatback screen with Bluetooth, USB-A, USB-C and 110VAC power at the seat, and complimentary Fly-Fi. The screens run the newest version of Blueprint by JetBlue, the airline's inflight platform.

Food depends on how far you are flying. FirstFare, the meal service, appears on flights of 899 miles or more with an entree, a side and a dessert. Shorter flights get the snack and drink program rather than a tray, so a short hop in BlueFirst buys you the seat rather than the meal.

The suppliers are named rather than generic: snacks from Sockerbit, Tosi, Wholesome Bakery, Pop Daddy Snacks and Cape Cod Chips, wine from Parcelle, coffee from Cometeer and Joe Coffee, and tea from Smith Teamaker.

Two features are genuinely new rather than repackaged. Seatback ordering lets you order from the screen instead of waiting for the cart. And Mixologist Mode builds a cocktail from a chosen spirit, mixer and flavoring, which is the kind of thing that either delights you or does not, but nobody else is doing it on a domestic narrowbody.

"Domestic first class has become easy to predict. We think it's time for a fresh take," said Joanna Geraghty, JetBlue's chief executive officer.

Which JetBlue Flights Get BlueFirst

BlueFirst is for the aircraft and routes Mint does not serve. JetBlue puts Mint on all transatlantic flights and on select coast-to-coast, Caribbean and Latin America routes, flown by the A321LR, A321neo and A321 Classic. BlueFirst covers everything else, which is where American, Delta and United have had a domestic first cabin and JetBlue has not.

JetBlue says initial routes and timing will be announced later this year. It has not published them yet.

BlueFirst vs Mint: How JetBlue's Two Premium Cabins Compare

These are not the same product at different prices. Mint is a lie-flat business class; BlueFirst is a domestic recliner first class. Confusing them is the easiest way to overpay or to be disappointed at the gate.

Mint BlueFirst
Seat Fully lie-flat bed, up to 6 feet 8 inches Recliner, five inches of recline
Legroom Suite with direct aisle access Up to seven inches more than Main
Layout Private suites on A321LR and A321neo; rows 2 and 4 on A321 Classic Two-by-two
Screen 15 inches or larger, 22 inches in the Mint Studio 13.3 inches
Dining Menus with Crown Shy and Birdee, cocktails shaken on board FirstFare on flights of 899 miles or more
Where All transatlantic, select coast-to-coast, Caribbean and Latin America Routes Mint does not serve

The front-row Mint Studio adds a mirrored vanity, extra storage and a guest seat with a table, and JetBlue calls its 22-inch screen the largest on a U.S. airline. Mint also carries amenity kits with Dr. Dennis Gross skincare and Master and Dynamic headphones on transatlantic routes.

The practical rule: if the route has Mint, Mint is the better cabin and it is not close. BlueFirst is not competing with Mint. It is competing with the domestic first cabin on a Delta or American narrowbody, and that is the comparison to make when you are pricing it.

Worth knowing before you book: a JetBlue route can have one or the other, not both. So the cabin you get depends on the aircraft assigned to your flight, which is exactly why the unpublished route list matters.

What JetBlue Has Not Announced Yet

These four gaps decide whether BlueFirst is worth planning around, and several have been filled in elsewhere with numbers JetBlue has not confirmed.

How many BlueFirst seats per aircraft. JetBlue has given a configuration, two-by-two, with no row count and no per-fleet breakdown. Without that number you cannot judge your upgrade odds, and upgrade odds are what most Mosaic members actually care about.

Whether Main cabin legroom changes. JetBlue has mentioned Main exactly once, as the thing BlueFirst has up to seven inches more legroom than. It has said nothing about Main pitch, total seat count, or Even More Space. Adding a premium cabin to a fixed fuselage usually comes from somewhere, and JetBlue has not said where.

Treat any specific Main cabin pitch figure you see quoted for BlueFirst aircraft as unconfirmed. JetBlue has not published one, and the seat map on a bookable route will answer it before any announcement does.

When your aircraft gets retrofitted. "First aircraft debuting later this year" is the whole of it. No program start, no completion date, no aircraft count per quarter. Until that exists, a route you can actually book is the only reliable sign an aircraft is finished.

How it prices and how it upgrades. Nothing on fare buckets, nothing on whether Mosaic members clear into it complimentary or on an upgrade currency, nothing on same-day upgrade pricing. For a TrueBlue member this is the single most consequential unknown.

What BlueFirst Means for TrueBlue Members

Nothing, and that is a real answer rather than a dodge. You cannot book it, you do not know where it flies, and you do not know how to get into it on points.

What you can do is stop assuming your usual JetBlue routine survives the retrofit. If you fly a route where Even More Space is your habit, watch the seat map on that route once BlueFirst aircraft start appearing, because the cabin layout in front of you is about to change in ways JetBlue has not yet described.

If you are chasing status partly for upgrades, hold. JetBlue Mosaic is worth having on its own merits and the tier requirements have not changed, but do not spend tiles on the assumption that a complimentary BlueFirst upgrade is coming, because JetBlue has not said it is.

And if you are deciding between JetBlue and a competitor on premium cabins today, Mint access through the BlueHouse lounges is a benefit that exists now, which BlueFirst is not yet.

What to Watch Before You Book

Three things, in order of how much they change the maths.

The route list, because it decides whether this is a product you will ever see. The upgrade policy, because it decides whether TrueBlue members get value from it or just a more expensive fare. And the Main cabin seat map on retrofitted aircraft, because that is where the answer to the legroom question will actually appear, published by JetBlue on a booking page, rather than asserted by anyone in advance.

We will update this when JetBlue publishes the routes.
