Quick answer: BlueFirst is JetBlue’s domestic first class, not Mint, with recliner seats in a 2-2 layout, 12 seats per aircraft, and up to 37 inches of pitch on the A220, A320, and A321. A family of four at intro pricing paid $996 in first class versus $856 in Main on LGA to FLL, or $140 more, and points bookings start at 27,000 TrueBlue plus $5.60 one way.

JetBlue finally did it. After years as the only major US airline without a domestic first class product, BlueFirst is now on sale — recliner seats in a 2-2 layout on the A220, A320, and A321, with the first revenue flight December 8, 2026 (Boston to Fort Lauderdale).

Before you get excited: the introductory fares ($249–299 one-way) had a book-by deadline of October 16, 2026 — that window has closed. What follows is the product guide, the family math, and what to watch for next.

What BlueFirst actually is

Let’s clear up the biggest confusion first: BlueFirst is not Mint, and it’s not lie-flat. Mint remains JetBlue’s lie-flat transcontinental/Europe product. BlueFirst is a classic domestic first class — recliner seats, 2-2 across, no middle seats.

• Seat: Collins Aerospace MiQ — the same seat American Airlines uses in domestic first. 12 seats (3 rows) on the A220/A320, 16 (4 rows) on the A321.
• Space: up to 37″ pitch (7″ more than Main), up to 5″ recline, Tuft & Needle Flex foam cushions.
• Tech: 13.3″ seatback screens with Bluetooth, USB-A/USB-C plus AC power, free fleetwide Wi-Fi.
• Food: FirstFare dining (entrée + side + dessert) on flights 899+ miles, seatback ordering with “Mixologist Mode” custom cocktails, sommelier wines from Parcelle.
• Priority: Group 1 boarding, dedicated overhead bins, priority check-in, expedited security at 30+ airports.

Three fare types: BlueFirst Base (cheapest; 1 checked bag, seat selection free within 24 hours of departure, change/cancel fees), standard BlueFirst (2 checked bags, free advance seat selection, no change/cancel fees), and BlueFirst Flex (refund to original payment, free same-day switches/standby).

The intro sale (what happened)

JetBlue opened bookings October 15, 2026 with promotional one-way fares:

• LGA–FLL: $249 (travel Dec 12, 2026–Feb 10, 2027)
• BOS–FLL: $299 (travel Dec 8, 2026–Feb 10, 2027)
• JFK–LIR (Costa Rica, outbound only): $299 (travel Jan 5–Feb 10, 2027)

Fares included government taxes and fees; availability was limited. Post-promo, AwardWallet found JFK–FLL BlueFirst at $364 versus $283 for Even More Space and $214 for Main — roughly an $80–150 premium over economy at launch pricing.

The family gotcha: blackout dates were December 17, 2026–January 4, 2027 and January 14–18, 2027. The intro fares excluded Christmas and New Year travel entirely — the exact window families fly most.

The honest downsides

1. All meals are served cold. The non-Mint aircraft have no ovens, and JetBlue isn’t installing them. American, Delta, and United all serve hot meals in domestic first.
2. Main cabin gets squeezed. The retrofits cut Main legroom from 32″ to 30″ and remove some extra-legroom rows to make room. If you’re flying economy on a retrofitted A320, you lose space.
3. It’s a recliner. Set expectations accordingly — this is not Mint, and JetBlue’s marketing lets the two blur together.

The family math

Here’s why BlueFirst is genuinely interesting for families: the 2-2 layout means no middle seats. A family of four splits into two pairs. No negotiating who sits in the middle. It’s the friendliest premium cabin layout for families in the domestic market.

At intro pricing on LGA–FLL: 4 × $249 = $996 in first class versus 4 × $214 = $856 in Main — the whole family flies first for $140 more than economy. A family of six: $1,494 versus $1,284, a $210 difference. That’s the kind of math that makes first class a real conversation instead of a fantasy.

On points: BlueFirst is bookable with TrueBlue points (revenue-based, no blackouts). A sample JFK–FLL search priced at 27,000 TrueBlue + $5.60 — about 1.33¢ per point, standard JetBlue value. A family of four one-way = 108,000 TrueBlue. And TrueBlue’s free Points Pooling lets up to 7 people combine balances — built for families.

Transfer partners (verified): Chase Ultimate Rewards 1:1, Citi ThankYou 1:1 (annual-fee Strata cards), Wells Fargo 1:1, Amex Membership Rewards 250:200 (loses 20% plus the US airline excise fee), Capital One 5:3 (loses 40%), and Rove 1:1 with a 20% bonus through November 14, 2026 — the best current ratio.

Mosaic changes

Mosaic members get complimentary space-available upgrades to BlueFirst on eligible fares. And the “Move to Mint” certificates are becoming Premium Upgrade Certificates, redeemable for either Mint or BlueFirst.

What to watch next

The intro sale is over, but this product will be on sale again — JetBlue runs fare promotions constantly, and a 30-route rollout through April 2027 means plenty of launch-route deals. The playbook: watch the new-route launches (especially FLL–DFW in February), compare the BlueFirst premium against Main on your dates, and remember the blackout lesson — promotional fares and holiday travel rarely overlap.
