The airline said the aircraft landed safely and all the 180 passengers and eight crew members have deplaned.
The crew of flight 9W-70 executed an air turn back to Mumbai on account of a 'suspected' tail strike, a Jet Airways spokesperson said in a statement.
The aircraft is being inspected by the Jet Airways Engineering team and ground personnel.
The Mumbai-Bangkok flight is delayed and is expected to take off at 1245 hours, the statement added.
This is at least the third incident of tail strike involving a Jet Airways plane this year.
