Break out your sleeping pills, because the longest domestic flight in the United States was just announced, and it’s a doozy. On Thursday, Hawaiian Airlines unveiled the “longest regularly scheduled domestic route in US history,” flying five days a week between Boston and Honolulu.

Clocking in at 11 hours and 40 minutes, the flight will cover a whopping 5,095 miles. Hawaiian Airlines hopes to make this long-haul flight as comfortable as possible for passengers, with 68 Extra Comfort seats in the main cabin with a 36-inch pitch, and 18-lie-flat leather seats in first class.

Currently, Boston is the largest US market without nonstop service to Hawaii. As nearly 500 people fly between New England and the Hawaiian archipelago each day, this new nonstop service is much overdue.

The Boston-Honolulu route will kick off on April 4th, 2019. Hawaiian Airlines is celebrating the route’s launch by offering special round-trip fares of $617 for main cabin seats, and $1,776 for first class. The tickets, however, must be purchased by Sunday, and are valid for travel between April 4th-30th 2019.
