Each carrier has their own luggage/baggage policy.
The best course of action in order to obtain this information is to read over the carrier terms and conditions provided on the checkout page.
BUS carriers will usually allow 1 suitcase to be checked into the lower portion of the bus and 1 small carry on bag that you can take on board with the price of your ticket.
Some bus carriers may allow you to check 2 suitcases instead of 1 for free, subject to space availability and most commonly seen on carriers that cover airport routes. Some of these carriers are Peoria Charger, Red Coach, Peter Pan.
TRAIN carriers, such as Amtrak, will allow passengers 2 carry on items and 2 small suitcases per adult passenger. For Via Rail Economy class you may only take 1 small carry on and 1 suitcase; all other fare classes will include 2 suitcases. If you are traveling on a Via Rail train with a checked car service, you may also check 2 additional suitcases.
Size and weight limitations are pretty general:
Carry on: 25 lbs (11kg) - Must fit under the seat/overhead bin. Book bags, purses, duffel bags are some examples (non-wheeled).
Suitcases: 50 lbs (22.5kg) - Actual size for checked baggage may vary by carrier but it is usually around 62 inches when you add together length + width + height. (Same as on an airplane)
Additional luggage: fees for additional luggage usually range between $10-$40 and vary by carrier. Some will instead require you to purchase a second ticket in order to check a second suitcase. Oversize and overweight luggage may also incur additional fees or even be rejected as it could be a safety concern for the handlers.
For more information you can also call the carrier at the number provided on your ticket, or simply look on their website under luggage or baggage policy.
We recommend that you properly tag all bags and place your name, address and phone number on the inside as most carriers will not be responsible for lost, misplaced or stolen items and insurance coverage is limited. You may contact the carrier directly to file a claim if this happens to you.
