Another Boeing 787 Dreamliner has run into issues. This time Poland's LOT LOT.UL airline had to make an emergency landing in Iceland on Sunday as the plane's identification system wasn't working.

According to Reuters, the plane was flying from Toronto to Warsaw but it never made it as it have to land at Keflavik airport in Reykjavik, Iceland.

"The aircraft had to land due to an air identification system fault. The Norwegian authorities have refused permission to fly over its territory, even though other countries gave permission to fly over theirs," Barbara Pijanowska-Kuras told Reuters

Boeing claims that the issue was due to an "inoperative antenna" which is used to send the plane's identification information during flight. The plane can fly with the antenna not working but air traffic controllers along the route need to pre-approve the flight according to Boeing.

"LOT has already made the proper arrangements and parts and personnel are
en route to address the issue and return the airplane to flight status," Boeing spokesman Marc Birtel told Reuters. "Boeing stands ready to help if asked."
The Dreamliner has faced several problems ever since it as introduced to the airline industry. The biggest issue was earlier this year when every Dreamliner had to be grounded due to battery problems.

Most recently, budget airline Norwegian Air Shuttle decided to take its brand new Dreamliner out of long-haul service over the weekend and asked Boeing to fix the plane after it broke down several times.

The Dreamliner problem is another issues for LOT as it has had huge operating losses over the past few years.

LOT is hoping that Boeing compensates them for lost revenue and they're giving the airline until the end of the year to settle or they'll take legal action.
Pijanowska-Kuras os LOT said the airline had to send two plane to Iceland to transport the Dreamliner passengers to Poland. Boeing says that it will try to fix the issue as soon as possible so that the Dreamliner can fly back to Poland as well.
