DENVER -- Fliers of Denver's hometown airline appear frustrated and fed up after reporting a huge number of complaints to the Better Business Bureau about the airline in the last several weeks.
Earlier this month, Frontier Airlines switched a computer reservation and check-in system which has prompted some delays for passengers online and at the airport.
"The complaints in our database are around customer service issues, delays in flights, or baggage claim issues," said a spokeswoman for the BBB of Denver.
The company is hoping to work with Frontier to resolve some complaints but passengers aren't wasting time and are hoping reviews posted online will get the company's attention.
"They're not what they used to be as far as I'm concerned," said Rich Strobe, a Frontier passenger who was reportedly stranded at St. Louis-Lambert Airport for 20 hours over the weekend.
The airline said in an online statement it is aware of some technical glitches but believe most problems have been resolved since switching systems in early March.
"We're still dealing with a few residual issues but we have a full-time IT team dedicated to correcting issues as they arise," a Frontier spokeswoman said.
