NEGATIVE star!!!!!!!\nWe booked our vacation package through Orbitz 3 months ahead. At that time,Spirit  Airline had the most fitted flight schedule,so we picked it. But we were notified the flight we booked was cancelled and we had to fly out the following morning. We were force to accept it&booked an additional night stay at Vdara. When we arrived at airport, they told us our normal size carry-on luggage cannot fit on the overhead bin. We had to pay $35.00 for each luggage both way!!! Then we tried to check in online for our returning flight the night before...our flight time changed to a night flight! We were shocked co'z we had to get back to work. So I called Spirit Air ... I was on the phone for more than an hour trying to get help. First the rep from overseas told me the flight had been cancelled. But i knew it wasn't true since i checked on flight  schedule online. Then they told me there was an error, our flight is overbooked& they can't do anything about it. How about that?!?! Then I called Orbitz,waited for 24mins before I get to speak to a person. Elise the rep was nice but not helpful. She 3 way called Spirit Airline but nothing can be done. So...we were forced to changed our plan twice. Second time without any notification at all. Don't ever fly with Spirit Airline!!!!
