Spirit Airlines was friendly in accommodating for our son’s peanut allergy. We flew in July of 2019.
We were permitted to pre-board the aircraft and wipe the seat/area down for past residue. Upon boarding, the flight attendants asked if we had any concerns. Then an announcement was made prior to take off to surrounding rows that they would need to refrain from consuming peanut products as there was a peanut allergy in the area. The crew was nice and friendly. We would fly them again.
