A third carrier option is available to Denver Air Connection travelers using Dubuque Regional Airport. According to a press release, Delta Airlines now allows travelers to book flights to and from Dubuque directly through the Delta website. Once travelers reach Chicago’s O’Hare International Airport on Denver Air, their ticket reservations and bags will transfer between Denver Air and Delta. Delta becomes the third major carrier, along with American Airlines and United Airlines, to have interline ticketing and baggage agreements with Denver Air.
