Forget fitness, 2019 may be the year you finally sleep well on the road.

Hotels, cruise lines, airports and even airlines are devoting more attention in the coming year to helping travelers get better rest when away from the comfort of their own bed.

Beating jet lag

Six Senses, with 14 properties globally, is rolling out a jet lag recovery program during the first few months of 2019 that it developed in consultation Dr. Steven Lockley, an associate professor of medicine at Harvard Medical School who is an expert on circadian rhythms.

The program is free, but guests must enroll in it before their arrival.

Lockley helped create a jet lag recovery app called Timeshifter, which tells users what to do to overcome their jet lag based on where they are in the world.

For example, the app indicates when to nap, sleep for the night and drink caffeine.

In 2019, Westin Hotels & Resorts, with more than 250 properties worldwide, will redesign guest rooms with sleep in mind.

New rooms will include special lighting with soothing illuminated patterns of light and shadow on the walls, like reflections on water, instead of the usual lamps and overhead lights.

Similarly, Four Seasons Hotels & Resorts offers free sleep-oriented amenities at all of its hotels.

Guests can choose among mattress toppers and pillows, each with different firmness levels.

Other amenities include lavender bath salts, pillow mists and eye masks.

Mood lighting in the skies

Airlines are also investing in cabin amenities that can help fliers sleep more soundly on long flights, or stay awake when it’s daytime.

Air Canada’s new fleet of Boeing 737s have cabins with mood-lighting systems meant to help travelers gently fall sleep and wake up.

On long-haul routes, the planes simulate a sunset after the first meal service and a sunrise before the second one.

Qantas and British Airways have new Boeing 787s with similar cabin lighting that also adjusts to the time in the flight’s destination.

The Airbus A350, a favorite with some airlines, is also built with passenger sleep in mind.

Delta Air Lines’ new A350s feature LED ambient lighting, and Singapore Airlines’ new LED lighting systems offer the cabin crew 16 million color combinations and the ability to simulate sunrises, sunsets and other times of the day.

Airports care about sleep, too

If you are stuck at an airport, now you can catch some shut eye in comfort.

Many airports are opening nap pods with beds that rent by the hour.

Hartsfield-Jackson Atlanta International Airport, for one, opened a new Minute Suites in Concourse T last September.

Located on the other side of security, the five suites have daybeds and sofas and can be rented starting at $42 an hour.

The co-founder of Minute Suites, Daniel Solomon, said that although the company opened its first location around nine years ago, and at the Atlanta airport, the bulk of its six locations have opened in the last 18 months.

Six more Minute Suites will open at airports in 2019 including in Charlotte and Baltimore.

In January 2019, Washington Dulles International Airport will debut a 16 room micro-hotel, Sleepbox, in Concourse A.

The rooms are 8-feet tall and 30 to 45 square-feet in size, have work spaces, are soundproof and have beds with memory foam mattresses.

Rental rates start at $25 an hour.

A second Sleepbox is scheduled to open in the second half of 2019 at Boston’s Logan International Airport.
