I'm not arguing which is more popular. I'm saying, that my word is travel. And your word is... Hm. It's hard to say it in english, because english language is complicated. For example:
Travel is one of the best activities.. In this case, word travel is путешествие.
I want travel... In this case, word travel is Путешествия.

As I've said, english is very complicated language, so you won't realize real difference, between these two words. But in russian, lithuanian, or other similar language, there are few difficulties, which english language hasn't. I'm not sayin, that word nутешествия is bad. But it is not real meaning of travel. Russians will realize the difference. Lithuanians will realize the difference, too. But english people - never.
