I am booking a flight from Sacramento to Lihue with 1 stop in Honolulu via Hawaiian Airlines. There are 2 options: 1.5h layover between the flights or almost 4h in Honolulu. The question is how often the flight are delayed and is it better to book earlier flight in a hope that if it doesn't make it to Honolulu on time they HA will put us (2 people) to the next flight. Or better book with the later flight ta make sure that we definetely able to get on it (what if it is ful??) and just wait for 4h in Honolulu airport? Anything from your experience?
