SAN JOSE, COSTA RICA - Frontier passengers flying from San Jose, Costa Rica to Denver were delayed for more than 24 hours by maintenance and customs problems.
Frontier Airlines flight 2087 was cancelled Sunday because of a maintenance issue, according to Frontier corporate communications manager Kate O'Malley.
Spencer Norman and Madison Cape tweeted that passengers had been delayed for nine hours. That was on Sunday.
A viewer told 7NEWS that passengers were eventually bused to a hotel on Sunday and told to come back on Monday at 3:45 a.m.
When they arrived, there were more delays.
"It took the agents over 2 hours to check [us] in," one passenger texted. "[Customs said] 10 people checked in too late even though we were all here at 3:45 in the morning."
Frontier Airlines said the new flight was scheduled to depart at 6:15 a.m.
However, a passenger sent 7NEWS photos that showed Frontier workers and customs officials on the tarmac outside the plane, then passengers getting on a bus.
"Passengers have been kept informed of the delay and are now in the gate area," said O'Malley.
O'Malley said Monday's delay was caused by Costa Rican customs.
"We are working with the customs department to get this flight on its way as quickly as possible," O'Malley said.
O'Malley said the flight was scheduled to depart at 11 a.m. However, passengers didn't reboard the plane until 11:15 a.m. The flight apparently departed around 11:37 a.m.
A group of junior high school students from Steamboat Springs is on the plane. They went to Costa Rica to build houses, according to a 7NEWS viewer.
