United Airlines expects to outfit its entire mainline fleet with Braille signage by 2026.
Braille will be used to denote aircraft rows and seats and will also be added inside and outside lavatories.
Thus far, United has added Braille signage on a dozen planes. The airline said it is the first U.S. carrier to utilize Braille in cabins.
The move earned praise from National Federation of the Blind president Mark Riccobono.
"The flight experience is often frustrating for a number of reasons, one of which is the amount of information that is available exclusively through printed signs and other visual indicators," Riccobono said in a statement Thursday.
"We hope to continue working with United to explore additional ways to make flying more accessible and less stressful for blind passengers.
United is installing Braille in concert with a broader overhaul of mainline cabin interiors.
