I will be travelling from Frankfurt to Luxembourg (changeover to bus in Saarbrücken) on Wednesday for a year-long stay and am trying to find out what the luggage rules are during the bus portion of this route. With train travel, one really isn't limited to luggage, and although there are guidelines, I've rarely seen these enforced. I have two big suitcases (that do meet airline regulations). However, I've found that some buses have different luggage rules from airlines.
Any information would be greatly appreciated. Thanks!
