The process for putting luggage on a bus depends entirely on the type of service you are using. For long-distance coaches (like Greyhound, FlixBus, or National Express), your large suitcases are stored in the "undercarriage" or "belly" of the bus. You typically present your bag to the driver or a baggage handler at the side of the bus; they will tag it and place it in the hold for you. You are usually allowed one small carry-on bag to take inside the cabin, which fits in the overhead rack or under your seat. For local city buses, there is generally no undercarriage storage. You must carry your luggage onto the bus with you. Most modern city buses have a designated "luggage rack" or a flexible "multi-purpose area" near the middle doors (often shared with strollers and wheelchairs) where you can stand with your bags. It is considered good etiquette to keep your bags out of the aisle to avoid tripping other passengers. Always ensure your luggage is labeled, as you are responsible for retrieving it when you reach your destination.
