For a 2026 traveler, the "standard" tip for a bus driver depends on the type of service provided. For a charter or tour bus driver who has handled luggage and provided local commentary over a full day, a tip of 10% to 20% of the total charter cost is customary (often shared among the group, amounting to $5–$10 per person). For an airport shuttle driver who helps with bags, a tip of $2 to $5 per bag is standard. For a private "party bus" rental, a 15% to 20% gratuity is expected and is often included in the contract, so check your paperwork first. For standard municipal city buses, tipping is not required or expected. In all cases, tipping is a gesture of appreciation for the driver's role in ensuring safety and navigating traffic, especially during long-haul excursions.
