If you're asking this question to yourself or to any person, then it would be the most despicable thought as well as one that will cost you some mega bucks if you do go on to turn a blind eye towards it. Still unsure? Consider this - There are innumerable flights from the UK, making to and fro and it takes just one moment of nature to strike a disaster or a financial trouble of your airline operator to doom your air travel. Unless you're some fortune-teller, it's not possible to predict an unforeseen event while on a journey and any unexpected event can turn a dream vacation into a scary nightmare.
