One of the 209 passengers, Erez Lieberman Aiden, told how they were woken in the night and asked to search their own luggage.
It did not emerge until later that there had been a bomb threat so passenger panic was not immediately sparked.
Erez said that the pilot attempted to reassure passengers as they came into land at Shannon Airport on Sunday.
Emergency services were waiting for on the ground for the plane's arrival.
It took around an hour for all the passengers to disembark before they were moved to a secure part of the airport as officials swept the plane.
No explosive devices were found on board.
Erez live-tweeted the event:
According to Sky News and the Mirror, a spokeswoman for Shannon Airport said: "The aircraft landed safely at 11.02am and all passengers have now disembarked from the aircraft.
"The incident is now the subject of a follow-up investigation by an Garda Siochana."
