I haven't flown since 2001 and I am finally taking a vacation to Greece next month. I'm debating if I want to get another battery for my laptop, but I wouldn't need one if there was power on the flight in both directions. I've confirmed that my United flight from EWR to FRA has power, but I can't for the life of me find a definitive answer on whether the Lufthansa flight (Airbus 340-300) from DUS or ORD has power in the seats.

Can anyone chime in? Hopefully I asked this in the right forum.

Thanks in advance!
