Yes, most major commercial airlines provide baby changing tables, though they are usually located in only one or two of the onboard lavatories. On narrow-body aircraft (like the Boeing 737 or Airbus A320), there is typically one designated restroom—often in the rear of the plane—that features a fold-down table located above the toilet. On larger, wide-body aircraft used for long-haul international flights, there are usually multiple lavatories equipped with these tables, often including one in the premium cabins. These tables are generally compact and made of hard plastic, so parents are encouraged to bring a portable, padded changing mat and a "wet bag" for soiled items. It is important to note that some ultra-low-cost carriers or very old regional jets may not have these facilities at all, making it necessary to change the baby just before boarding. Flight attendants can usually point you to the specific lavatory equipped with a table, and for safety reasons, you should never attempt to change a baby on your lap or on the tray table at your seat, as this is unhygienic and dangerous in the event of sudden turbulence during the flight.
