"Obviously, we were all concerned though after about one hour we were told the suspect package was safe.
"Everyone was relieved and we reboarded the plane."
SAS spokeswoman Cathrine Sandegren told the Standard: "During the flight a thermos was found on board and since the crew could not identify to whom it belonged it was decided to divert to Dusseldorf, the nearest airport, for a security landing.
"This approach was fully in accordance with our safety procedures. It was a completely normal landing.
"The police searched the plane and found that the thermos only contained water. All passengers were debriefed by the captain and had the possibility to ask questions .
"The plane was approximately 1.5 hour delayed to Alicante. We regret that the flight was delayed with 1.5 hours, while making our best efforts to inform passengers about the situation and take care of them in the best possible way."
