Delta, Hawaiian and American Airlines are offering some discounted prices on flights to Hawaii. You can fly for as little as $246 round trip, and there’s availability in August, September and October. These are Basic Economy fares, so they’re not suited for everyone. But if you can do without checked luggage and assigned seats, then it could be a good deal.
The cheapest fares are from Seattle and Los Angeles.
To find the cheapest options, start your search on Google Flights. You can then proceed to book directly from the airline or an OTA. If you have a Chase Sapphire Reserve card you can also book on the Chase Travel Portal starting from 16K Chase Ultimate Rewards.
I’m posting from my phone so I’m not including any example fares.
