Policy for Overweight Passengers

Allegiant “Passengers who are unable to lower the armrest and/or compromise any portion of the adjacent seat(s) should purchase an additional ticket during the initial reservation. Two seats will be pre-assigned (at no additional charge) in order to ensure the Passenger of size has two seats side-by-side. In the event, the flight is sold out and an extra seat is unavailable, the passenger of size shall be denied travel in the interest of safety.” – ALLEGIANT Passenger of Size Guidelines
