I actually used my JetBlue TrueBlue points to book a Hawaiian Airlines flight last year when visiting family in Honolulu. At first, I couldn’t figure it out online — some routes showed up, others didn’t, and I wasn’t sure if the points would transfer. Rather than risk messing it up, I called 844-734-0813. The rep explained exactly which flights I could book with my JetBlue points since Hawaiian is a partner, and they walked me through applying them. It was surprisingly smooth once I had someone guide me, and I even managed to tweak my return date without much hassle. So yes, you can definitely use JetBlue points for Hawaiian, but if you’re like me and don’t want to waste hours searching, that number is the fastest way to instantly book, cancel, or modify your trip.
