Just to follow up on my previous post, perhaps it's easiest just to list the planes on which you won't have 2Ku wifi when flying to Hawaii. As of 10/3/2022, if you're on any of the following dozen 737-800's, you won't have 2Ku wifi:
N534AS
N536AS
N537AS
N560AS
N563AS
N564AS
N579AS
N583AS
N584AS
N586AS
N593AS
N596AS
If your flight to Hawaii is not on any of these and you don't have 2Ku wifi, then either it's busted or you're on a MAX9 which was only recently brought into service (they don't come with 2Ku wifi enabled off the assembly line, and it seems to be taking AS about 1-2 months after initially bringing them into service to retrofit/enable the capability).
