Apparently it is very common practice that United Airlines overbooks their fights and today was no different. My flight was overbooked by 4 people and I was in no rush so looked into delaying my flight. Attendant Britteny looked up the flights and told me my flight would arrive 25 min later than my originally booked flight. No problem, so I changed and allowed someone to have my seat. That was at 1:30 pm. Now it is 6:25. At no time was I informed that Chicago was having bad weather. This came later and I was bumped once again. If I had been told that the Chicago flight was experiencing bad weather I would not have given up my seat. Shame on United Airlines and their HORRIBLE business practices. I have no idea if I'll make it to Denver tonight or not. But one thing is for certain. I will not be flying United Airlines any time soon. Do not fly united airlines.
