The Island's Airport has issued advice amid UK Border Force staff strikes.
Airports including Birmingham, Gatwick and Manchester will be affected up until New Year's Eve as around 1,000 staff walkout on eight days.
It says flights from the Island to these destinations shouldn't be affected, but knock-on effects could cause delays, especially at peak times.
Those traveling are encouraged to frequently check the status of your flight, and expect disruption through passport control when arriving to the UK from international destinations.
