Even though I booked a trip via delta to Lihue, they contract with another airline for the last leg. It is NOT a partnership with Hawaiian Airlines. Delta got us to Honolulu late, and HA really didn’t care. I should have been rebooked automatically. Instead I had to walk 4 miles back and forth trying to get on a flight and to get a hotel voucher.
