<font color=navy>The fires are in the mountains & hilly areas to the east and north of the Los Angeles/Orange County areas, and nowhere near Disneyland itself. John Wayne airport is between Disneyland and the ocean, so there is no danger there, either.
The problems they were having with the planes coming in stemmed from a control tower (in another place) going down (not burned), and this affected the flights coming in, and since LAX is sooo busy, this really affected them adversely. John Wayne and Ontario have been affected, but nothing like LAX, and I think there were no cancellations, but some delays.
The worse happening in Anaheim right now is the smell of smoke, and it really isn't due too much to the proximity of the fire, but more to the enormity of the fire, and even more, the direction of the wind.
Starting tomorrow, and surely by Thursday, they're expecting the direction of the wind to shift back to normal, (as opposed to the current Santa Ana condition), which means that the breeze will come off of the ocean, and push the air east, which should clear the air in Anaheim.
The areas hit hard here are the San Bernardino Mountains (to the east), Simi Valley (to the north), Julian (between Los Angeles & San Diego - but inland), another area east of San Diego, and other areas here & there.
