Where Can I Find Information About If Strike Will Delay My Flight
Strikes, industrial action, and wildcat strikes by all the different people who work
at the airport that you plan on travelling from can have a serious impact on whether your flight will be cancelled or not. In the run up to a strike airlines will assure the public that everything will go ahead as planned and that there will be no delays, but you should not entirely place you trust in them.
Your best source of information in the weeks running up to a strike that could threaten your travel plans is the mass media. They will be able to give you a good idea of example how advanced negotiations between unions and airline or airport management are. The media will be able to advise you if it looks really like a strike will happen, or it will be able to suggest if it thinks a conflict will be resumed. You can check websites like Google News and search the terms related to your airline, the strike, and the airport that you intend to fly from to see if flights from Miami to Buenos Aires or flights from Dallas to Fort Lauderdale will be proceeding as planned.
When you get up to a few days before the strike is planned to happen you should turn away from the media and instead turn to the airline itself. In the weeks running up to a strike they will explain that the negotiations with a union will fail, in order to be in a better bargaining position. But eventually they will accept that some flights will be cancelled or delayed.
By logging onto the website of the airline that you intend to fly with you'll be able to find out if you should postpone or reschedule flights from Saint Louis to London. Then you won't feel like a fool when you find the strike is happening on the day that you travel.
