Lufthansa's new first class suites will have closeable doors that offer passengers a private dining experience on caviar and other gourmet foods at a restaurant-style table when the new premium seats debut next year on the German flag carrier's long-haul flights.

New first class suites, business class suites, and economy class sleeper seats will debut in 2023 as part of Lufthansa's nearly $2.5 billion investment in premium products and services.

The new first class and business class suites are being rolled out as part of Lufthansa's new "Allegris" premium product line on long-haul routes.

For the first time in Lufthansa's history, the first class suites will have closeable doors that nearly reach the ceiling. Passengers don't even need to leave their suite to change into their Lufthansa first class pajamas before going to sleep. 

The forward-facing seats in the first class suites will be nearly 39 inches wide and can be converted into a bed. Every Lufthansa first class suite will have a large personal wardrobe for storage during the flight.

First class suite passengers can sit restaurant-style across from each other at a large dining table. Caviar service is available as part of the gourmet menu offerings.

A big-screen TV extends across the full width of the suite for in-flight entertainment. Wireless headphones can be connected via Bluetooth.

Lufthansa business class will also get a new front-row suite with higher walls, closing doors, a personal wardrobe, and a 27-inch monitor screen.

The economy class Sleeper's Row also gets new seats with a 40% larger reclining surface.

Lufthansa will replace more than 30,000 seats as part of the largest fleet modernization effort in the company's history.
