As it contends with slashed levels of airline service, Bradley International Airport has cut costs in a number of areas in response to its declining revenues. The financial strain will not dissipate in 2021, but airport officials are hopeful that the adjustments will safeguard the Windsor Locks hub’s finances and persuade airlines to make long-term commitments. A total of about 2.1 million travelers passed through Bradley in the first 10 months of 2020, down 63 percent from the same period in 2019. At times in the past 10 months, Bradley’s daily flight volume has plunged more than 50 percent from levels before the pandemic, according to CAA officials. Reflecting the severe restrictions on international travel, Aer Lingus and Air Canada have suspended their service at Bradley. Domestic carriers American Airlines, Delta Air Lines, Frontier Airlines, JetBlue, Spirit Airlines, Southwest Airlines and United Airlines are still operating there. Bradley is facing financial pressure amid the drop-off in flight activity. In the quarter from April 1, 2020, to June 30, 2020, revenues fell about $10 million short of projections. In response, the airport has reined in costs with an initial 10 percent cut in operating expenses and then an additional 10 percent cut, a hiring freeze, as well as deferred salary increases for non-union staff.
