Qatar Airways has bowed to pressure and scrapped contracts that permit it to sack flight attendants when they become pregnant.
The practice, which was outlawed in the US as far back as 1978 and is now illegal in most countries, follows a campaign by the International Labour Organisation.
Other clauses including a requirement for female crew members to tell the airline if they planned to marry in their first five years of employment are thought to be still in place.
The ILO had also asked the airline to review a ban on female cabin crew being dropped off or picked up from work by men other than their family.
The airline’s chief executive Akbar Al Baker has previously said he did not “give a damn” about the ILO and claimed it had a vendetta against the airline and his country.
