I mentioned it the other day, but... Magnetic fields do not work this way.
The LHC is 180 miles away, and had been on for five days when this happened. Thousands of planes passed through that radius without a problem, and hundreds were in the air at the moment this happened.
But before it could affect planes, the first thing it would cause is a power outage in the Geneva suburbs above the tunnels, possibly some computer damage. If it were strong enough to bring down a plane 180 miles away, it would have been crippling power grids in most of Switzerland and big chunks of France, Germany, Italy, and whatever countries in the area I forgot from high school geography (Austria I think?). The power outage would have been one of the largest ever.
Unless Doctor Doom just took over CERN, I think we're fine (dibs on the Avengers 4 idea).
Yep, however the LHC was never restarted because a short circuit in one of the magnets was discovered during a systems check on 3/21, a few days before the plane crash.

Days before it was supposed to start circulating protons again after a two-year hiatus, the world's largest particle accelerator has developed a short circuit. The team behind the Large Hadron Collider (LHC) is now evaluating its options to determine whether the problem will cause a delay of days or months.
“An intermittent short circuit to ground in one of the machine’s magnet circuits was identified on 21 March and is under investigation,” says a 24 March statement from the CERN, Europe's particle-physics lab near Geneva, Switzerland, which hosts the LHC.
