Why do we have the layovers (in one word) and stop-overs (hyphenated) tags? Maybe it would be nicer to have both in one word or both hyphenated. I don't have the rights to change it myself though.
suggestion: layovers stopovers
EDIT: I don't ask about the difference of meanings, there was this question a while ago that states the difference, as @Ankur Banerjee underlined it.
