I found the folowing sentence.<br/><br/> "Although handling arrangement at UK airports are excellent, there are rare occasions when your baggage may unfortunately be delayed."<br/><br/> I think it should be "Although handling arrangement<i>s</i> at UK airports are excellent..." or "Although handling arrangement at UK airpots is excellent..."<br/><br/>Is the word, arrangement, used as an uncountable noun? If so, why is "are" used in the original sentence?
