Lufthansa will no longer greet passengers with "ladies and gentleman", but switch to gender-neutral language instead.
Crew can still use 'sir' and 'madam' but can decide depending on context and situation such as the landing region and destination.
A list of various alternatives have been prepared, which include addressing passengers as 'guests', or greeting simply with a, 'Good morning here on board".
Even the company's internal communications and contracts have applied these linguistic changes.
The move goes across the group's airlines: Lufthansa, Eurowings and Brussels Airlines.
"Diversity and equality are core values for our company and our corporate culture. From now on, we want to express this attitude in our language as well — and show that diversity is not just a phrase, but a lived reality," read a corporate statement from the German carrier.
Other carriers which have done the same include Japan Airlines, EasyJet and Air Canada in an increasing global acceptance towards diversity.
In June this year, a Federal Aviation Administration committee report on the drone industry suggested changing aviation terminology to more gender-neutral ones, such as 'airman' to 'aviator', or 'unmanned' to 'unscrewed', according to a Washington Post report.
