To my astonishment, I was granted a ride on Hawaiian and Aloha recently. I was not allowed to greet and thank the Hawaiin crew, but they gave me a ride across the pond, so I thank them for that even though they wouldn't talk to me.
Aloha crews have almost always been friendly to us. I was given an inter-island ride recently and the whole crew was nice and friendly.

As the politics heat up in court, the tension on the inter-island ramp has increased. I am sure we'll have more jumpseat denail stories in the near future.

As a side-note, I have given Aloha crews a ride on a few occasions, very friendly and professional.

As far as CRJ CA seniority goes, it is a mixed boat. OGG and ITO are realtively senoir (I couldn't hold OGG and I have been here nearly 7 years). LIH and HNL (reserve only) are realtively junior...junior CRJ captains there have roughly 2.5 to 3 years with the company.
Things may change within the next six to nine months. All bases (except KOA) are at minimum staffing and 10 days off a month, with no time to go to the mainland. Burnout is getting high and many may bid out of the system. Replacements will probably be junior. On the other hand, if PHX eventually shrinks some with displacing pilots & the CR9 comes out here, I can see this system going senior.

Hope it helps.
