Airfare deals are typically only available on limited dates. We recommend you use Google Flights to find dates to fly, then book through an online travel agency such as Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using The Platinum Card® from American Express, you’ll need to book directly with the airline or through Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.

Wednesday night, we wrote about how American began attacking fares from Delta hubs. Thursday morning, Delta responded with an attack on AA hubs. Now, we have an all-out fare war for flights to Hawaii. Right now, we’re seeing 22 US cities with tickets available to Hawaii for under $400 round-trip, with even more cities added each time we look.

Dates vary by departure city. Most of the outstanding deals are limited to departures from January through March 2018, but make sure to look at the calendar on Google Flights to see which dates work from your city. Then you can complete booking directly with the airline.

Airline: Alaska, American Airlines, Delta, Hawaii
