LONDON (AP) — Airlines say they are canceling some flights in and out of London's Heathrow Airport ahead of a nationwide public sector strike on Wednesday.
Heathrow's owner, BAA, warned last week of possible 12-hour delays moving through immigration because the strike is expected to cripple the U.K. border agency. It has asked airlines to fly half-full planes into Heathrow during the strike.
Middle East carrier Etihad Airways says it has canceled two flights from Abu Dhabi and one flight from Heathrow to Abu Dhabi to spare customers any disruptions.
Greece's Aegean Airlines said it canceled one Heathrow to Athens flight and one from Athens to Heathrow because airport authorities warned of "potentially huge problems with delays."
