Applies to Travel for sure. Personally I think if you have the "award" or proof that you own the status as No 1 then use it. Your title tag is like your sales pitch. If you sell shit to me and you are the No 1 or the Best and don't say it, you might have missed new customer. I am more likly to click on something that claims to be No 1 or the Best, however, if I get there and it isn't true then bey bey. So I don't think it could hurt unless it's not true.
