The plane left Edinburgh shortly at about 7am but was forced to declare an on-board emergency soon after.
On twitter, International Flight Network wrote: “Easyjet flight U26931 from Edinburgh (EDI) to Hamburg (HAM) has declared a general emergency and is returning to Edinburgh.”
It then added: “Update: Easyjet flight U26931 from Edinburgh (EDI) to Hamburg (HAM) returned to Edinburgh due to a ‘crew welfare issue’.”
An EasyJet spokeswoman said: “easyJet can confirm that flight EZY6931 from Edinburgh to Hamburg returned to Edinburgh after take-off as a result of a crew member requiring medical assistance. Following a routine landing, the aircraft was met by medical services.
