They remain an issue in hotels including in the aforementioned cities and yes I agree we don't know when they boarded, presumably if they were only confined to one chair the chances are recently.
I agree with the majority here, it is not the airlines fault that this is a problem, but the way they deal with is what we should judge the airline by; 48 hours I'm afraid is unrealistic at such times of the year but I hope they contact you soon and you get the resolution you are looking for.
