DENVER - A thousand people were stranded at Denver International Airport overnight.
The bulk of those (794) were traveling on United which had to cancel about 23 flights out of DIA, airport officials confirmed Tuesday morning.
Countless people turned to Twitter and Facebook to complain to United Airlines about the delays.
"@united you stranded my mother in Denver and told her it would be 2 days. Kept her bag and her meds. Fix it," Andy Eppler tweeted at 12:45 a.m.
"It's a mess here. No food/water services available and everyone has to sleep here tonight," Kelly Walsh told 7NEWS. "Blankets will be distributed to children and elderly because hotels are full."
"@united I want to change cancelled flights and have been on phone for three hours. Stuck in Denver. Help please!" Nick Hartley tweeted early Tuesday morning.
United's Twitter feed was full of similar messages from travelers in Denver, Chicago and Houston.
"We're currently experiencing high call volumes due to the weather delays. We´ll assist you as soon as possible," United tweeted in response to several complaints.
"Please send us a DM with your confirmation number and we'll take a look into this. We appreciate your patience," was another typical response from United.
"Hotel vouchers are not provided when weather or reasons out of our control cause delays or cancellations," United stated on Twitter.
Tuesday morning United responded to our request for information.
"Heavy storms in our system prevented us from operating flights out of Denver last night. We are working to reaccommodate our customers as quickly as we can," said Charles Hobart, spokesperson for United Airlines.
