To get a free upgrade on JetBlue, the best approach is to achieve Mosaic status through their TrueBlue loyalty program. Mosaic members can enjoy complimentary upgrades to Even More Space or preferred Core seats, depending on their tier level, and can also extend these benefits to up to eight companions on the same booking. While upgrades are based on availability, there are specific rules for when and how you can select upgraded seats.
- Mosaic 1 Customers can choose preferred Core seats at booking for free, except when flying on a Blue Basic fare. They can also select Even More Space or preferred Core seats at no extra charge within 24 hours of travel, pending availability, unless traveling on Blue Basic fares after March 1, 2025.
- Mosaic 2 Customers and above are eligible to select Even More Space or preferred Core seats for free at the time of booking or afterward, depending on availability, except when flying on Blue Basic fares (starting March 1, 2025).
- Companions: Mosaic members can extend these free upgrade benefits to up to eight companions on the same PNR (booking) as long as they're not flying on Blue Basic fares after the March 1, 2025 deadline.
These upgrades are subject to seat availability and do not apply to Blue Basic fares starting in 2025.
