Wheelchair assistance in 2026 is a complimentary service provided by airlines to help passengers with limited mobility navigate the often-massive distances of modern airports. When you request this service (ideally 48 hours in advance), an airport attendant will meet you at the check-in counter with a wheelchair and escort you through security via priority lanes, all the way to your departure gate. There are three standard levels: WCHR (for those who can walk but not long distances), WCHS (for those who cannot climb stairs), and WCHC (for those who are completely immobile). The service includes "aisle chair" assistance, where a narrow wheelchair is used to move the passenger from the jet bridge to their actual seat on the aircraft. Upon arrival, the attendant meets you at the plane door and assists through immigration and to the baggage claim. While the service is free, it is customary in 2026 to tip the attendant $5–$20 depending on the complexity and duration of the assistance provided.
