I love United Airlines and have flown them since I was two years old. But currently, United is faced with the same challenges that other carriers face. As the official airline of the DNC Convention, United is on the hook to perform well.
The last time I was in Denver for the Invesco visit, there was an enormous customer service line unlike any I've seen before. In this video, I explain how you can avoid that problem. There are several steps:
1) Plan ahead and know what flights are coming in and out.
2) Come to Denver early, like the 23rd of August or the 22nd.
3) Take the Red-Eye. Avoid on-peak hour travel.
4) Get the United customer service number and save it. It's 1-800-864-8331 for domestic flights, and 1-800-426-5561 for Spanish language persons, 1-800-426-5560 for Asian speaking persons, and 1-800-323-0170 for persons who may be deaf or blind.
There's no reason why your trip to the DNC Convention can't be a good one. Plan ahead. See you there.
