Here's a worst-case scenario- You're on business in another country and you need to get back for the weekend because it's your sister’s wedding. But there's a terrible snowstorm during the night and your flight home is cancelled- What should you do? OK. The first thing’s prevention. Always be aware of the weather conditions where you're gang and, for your own peace of mind. Check the weather reports before you travel in case there are any bad forecasts. Checking that your flight operator or travel insurance company covers you for such eventualities is also a good idea. Any reputable company should be obliged to look after you in these circumstances. Although I'd say, generally avoid using low-cost operators because asserting your rights can be more difficult with them. What to do about it is more tricky. I'd strongly advise against finding alternative routes home. The chances are that everyone else is thinking the same thing and that boats, buses and trains will also be affected by the weather conditions. So the best thing is to sit tight and wait it out. Try to make friends with someone else in the same situation. It may be helpful if you're having to spend hours waiting at an airport and will keep you in a better mood when you go to speak to the harassed ground staff. Lastly, if it's going to be a lengthy wait at an airport, consider finding an executive airport lounge and paying the €30 or whatever they ask for non-members.
