Continental Airlines Sucks

I wouldn't recommend this airline to anyone in my dream also. I had a such a bad experience flying with them, I can't imagine to ever happen to me again. I had to reach to attend a ceremony and can't afford to miss that, I was at the airport 40 minutes before and the crew at airport didn't let me in say I was late as the gates are closed 35 minutes before departure, because they thought the flight was at 3:40 where in it was at 3:45 and I reached the airport at 3:05.
