I think I've been working too long today. I read that headline and stared at it for a good 10 seconds trying to figure out why on earth airlines would be "un-ionized".
"In his essay To Tell a Chemist (1965), Isaac Asimov [7][8][9] claimed that one could distinguish a chemist from a non-chemist by asking a person to read the word "unionized" aloud. With no context given, he said that a chemist will pronounce it "un-ionized", but a non-chemist will pronounce it "union-ized"." --Wikipedia
