On my flight from pittsburgh to tampa I was so disappointed in the filthy condition of the plane. It was gross! I realize this is a cheap, no frills airline but this was inexcusable. I couldn't even follow along on the safety card, that they encourage you to do, because it was dirty and sticky with who knows what. The other cards in my row were just as bad so ummm no! The interior walls, floors, seats, seat backs all were discusting. I had to put my larger purse under the seat in front of me for takeoff and landing and I could barely stand it!! The middle aisle floor was disturbing to even look at. I am not a picky person and was not expecting a luxury experience however I was also not expecting this level of filth! YUCK!!! To be fair I need to add that on my return flight, of course I feared the worse but had no choice. I was very pleasantly suprised to find this plane very clean and pleasant to fly on. So, be prepared. You just will not know the condition of the plane with this airline until you board. Allegiant needs to be more consistent in keeping up with the cleanliness of there planes! Fly with Allegiant at your own risk and bring lots of hand sanitizer!!
