For all you who travel to Cozumel during Spring Break, heads up. Husband and I flew Frontier Airlines down to Coz, Sat., March26, no problems. Flew with Apple Vac., but this plane was NOT an Apple charter, and not an Apple problem. Apple uses that plane to go to Coz on direct flights. Stayed one week at IB Cozumel...loved it, but been there before, husband is a diver. Now comes the unexpected disaster. Return Frontier flight scheduled for Sat., April 2 and picked up at hotel by 1PM for 3:30 Pm flight. All is well, got through in fine shape with security and on plane on time, though several other flights going back to the states had been delayed. On plane, ready to take off, and announcement comes on that plane would be delayed due to flight attendant had become ill and paramedics were being called in for evaluation. The fifteen minutes went by, then came another annoucement, the whole plane would have to deplane and take all carry-on off plane as the flight attendant was being taken to hospital, and Frontier could not tell us what would happen next until 2 hours from then. Not a good sign. So we all get off, file back into the airport, and now only 2 flights are left to fly out of the airport for the night. Unfortunately, when this happens, the airport is so small with only a few flights out a day, when those flights were out, the whole airport closes for the night and NOTHING is open. Those flights are on the way out, and we still have no feedback. FINALLY, almost 4 hours later from the scheduled departure, we are told by Frontier that we need to go back to luggage claim and claim all our checked bags and return to the Frontier Customer Service counter in the airport as they would issue a voucher for TWO nights in a hotel, as there were no flights out of Cozumel back to Denver until Monday, and that was it. You did not want to see the chaos that came next...it got UGLY. In the meantime, the explanation was that because the flight attendant could not go back to work, due to the lack of anymore flight attendants in the area including Cancun, there was no back-up for a flight back to Denver the next day as that plane only flies Sat., Mon., and Thursday. That plane had to go back to Denver with its crew as the plane was needed for another destination the next day from Denver, and could not stay in Coz.. So ,Bye-Bye plane and crew, and passengers are stuck in Coz. for 2 more days because there wasn't enough flight attendants available because one was ill. Rumor had it that they checked Cancun, but any extra flight attendants with lay-overs were out drinking...great! So, for the next 3 hours we all cattle-herded into lines for agents to try to scrounge around and find over 150 people rooms for 2 nights in Coz until they could get a plane out sometime on Monday. Of course, being Spring Break, it was a nightmare tryng to get hotels for all of us. In the mean time, the agents that were suppose to be Frontier, really were agents for all airlines that fly in and out of there, so they were clueless. They had collected our immigration forms out of the country and exchanged them for boarding passes, but when we came back into the airport, they could not give our immigration papers back as they said they had over 1,000 of them to look for and could not possibly produce them as the airport was closed. So, not only are we in line to get hotel rooms, but also illegals in the country..and no paperwork except our passport. If we wanted to fly out of Cancun, we would need that immigration paperwork. One poor man had scheduled surgery in California as several families on the plane were from there, and he had no way to get back to his home now for surgery for Monday morning. Finally, after our scheduled departure for Denver at 3:30 PM was cancelled, we finally left the Coz airport At 11PM in a taxi for a flea-bag hotel in the middle of San Miguel at midnight. The passengers were scattered all around the town, but were issued a voucher to eat our meals just for our plane at one particular hotel not too far from the hotels they put us up at...but it was not pick your meal off a menu, it was a small buffet the hotel put on just for our plane passengers. To say the least, it was recycled salad, soups, and hot dogs. Not a good impression for Frontier after all we had been through. We were put up at probably at the worst hotel, box air conditioner in the room that barely worked and a rock band that played all night outside our hotel, but able to change the next day to the main hotel where most passengers were put up. But we had to drag our 4 bags through 5 blocks in San Miguel through the alleys just to get to the hotel the next day, as no one offered any taxi to do this. We got in around 2PM, then Frontier said they would pick all passengers up at this hotel at 3AM Monday morning as they arranged a special flight for all of us back to Denver Monday morning at 5:45 arriving Denver at 9AM. That went smooth, only plane in the airport at that hour, as we opened the airport with our flight. We didn't get ANY food on the flight back, however, we were issued vouchers for the trip, but the flight attendants were clueless on how much the vouchers were for and they said that to us. Not a good crew or customer service for Frontier. So, just a heads up to anyone that flies to Cozumel, if you get stranded there, don't count on getting back the next day...since it is an island with very few flights, they only fly when their scheduled flights are due for the days they are scheduled. Good Luck!
