Yes, Swoop offers three different wheelchair services to get you to and from check-in to the aircraft:

• Wheelchair; can walk up steps.

  The primary purpose for the wheelchair is for distance. You can walk up and down stairs unassisted and move to/from your seat to the aircraft door/lavatory.

• Wheelchair; no steps.

  This request indicates that you cannot walk up/down stairs, but can move to/from your seat to the aircraft door/lavatory.

• Wheelchair; carry on.

  This request indicates that you require a wheelchair upon check-in to get to/from the aircraft and require transfer services up/down stairs, into the cabin, into your seat and to/from the lavatory.
