Left my house at 7:00 pm Sunday for a 8:25 pm Allegiant flight at the Rockford (IL) airport. Love that airport - free parking, no lines at check in and within 25 miles of home. The incoming flight was one hour late - a bit of disappointment, but nothing too terrible. With the 2-hour time change, we'll still get to Vegas before midnight. We board and I was pleased to have an empty seat next to me. So far, things are relatively fine...until the plane taxis to the runway. Even though it was an unseasonably warm 40 degrees, the plane had to be de-iced. We wait for this de-icing, but it never happens. Instead, the cabin lights are shut off for some reason. But, they won't go back on. Pilot says we can still fly without them, but heads back to gate for mechanics to check out. It is determined that the batteries need an 8-hour charge and there is no other Allegiant plane in the vicinity to use. The flight is now rescheduled for 8:30 am the next morning. Those passengers from over 50 miles away are to receive hotel vouchers and the rest of us are told to go home and come back in the morning. When you're the only flight at a small airport on a Sunday night, there wasn't a lot of customer service available and I get that. By then, I lost my interest in traveling and after arriving back home at 10:30 pm, decided not to go back in the morning. Oh well, there will be other Vegas trips. One disappointment, though, will be missing first-ever "vegas get-together" between HoyaHeel and myself. We've known each other for over 10 years on this board, but have never met in person. Only other casualty was forfeiting first night's stay at the IP for a grand total of $18. Actually, just as I finish writing this is about the same time the regularly scheduled flight would have landed and I would have soon been on my way to catch the CAT.
