The dispute over pay and conditions is expected to cause major disruption, mainly to arriving passengers, with the army and staff from the Home Office and other contractors on standby to help out if needed. However, so far things seem to be running well.
Gatwick Airport said that the airport is running smoothly, a spokesperson for Heathrow advised "The morning arrivals peak has started well. Immigration halls are free-flowing at Heathrow with Border Force and the military contingency providing a good service." Glasgow Airport said regarding the proposed strike dates beginning today: “We do not anticipate any significant challenges for passengers travelling through international arrivals as a result of the industrial action being taken by Border Force staff. Mitigation measures are in place and additional Glasgow Airport staff will also be on hand to ensure any unlikely disruption is kept to an absolute minimum.”
There were some delays at Birmingham, but Manchester seems to be operating normally with security wait times currently 0-15 mins in all three terminals.
