Boarded the plain and had to wait 1 hour for crew Captain to arrive from another flight

The space for legs in coach is better than other Airlines you can even cross your legs!!

Comfortable seat, plenty of leg room which is so rare, overhead bin comfortably accommodated my carry-on bag. Deli box was tasty, service was good, bathrooms were clean. Uneventful flight, which I appreciate. Departed on time and landed early.

Honestly, there was not much they could do. Due to wind, the flight was delayed for several hours because we had to be diverted to San Jose where we needed to refuel before departing to Hawaii. Wish they had offered some snacks during the delays/diversion because we had to wait such a long time to finally get our food served during the flight after leaving California.

They canceled the flight 30 minutes prior to departure without any heads up.

All parts were excellent, especially staff at bag tag printing and inflight crew. Just the normal differences from past air travel could be improved but we’ve learned to accept those—cramped seats, minimal food/beverage, etc.

Better organizing of entry and exit onto the plane regarding all of the baggage people haul on. There should be a better system so those with no baggage can get in and out more quickly. The baggage haul-on situation is absurd.

Attentive crew. Best of all was the empty seat between me and my rowmate.

We had a very scary attempted landing in Palm Springs and were redirected to Ontario. It was a stressful flight.

Every thing means , crew, service, timing, boarding is very good.
