When it comes to flight delays, the compensation you may be entitled to can vary significantly depending on where the disruption occurs and the regulations that apply there.

In the United States, there is no federal law requiring airlines to provide passengers with money or other compensation when their flights are delayed. However, each airline has its own policies about what it will do for delayed passengers. If you're traveling within or from the United States, it's advisable to check with the airline for their specific policy.

In Europe, the situation is quite different thanks to EU Regulation 261/2004. This regulation stipulates that passengers are entitled to certain rights and compensations for flight delays over three hours. In the event of such a delay, the airline is obligated to provide you with meals, access to phone calls, and even accommodation if an overnight stay is necessary. For delays that are within the airline's control and exceed three hours, financial compensation may also be due.

As for Asia, the regulations can vary greatly by country, and they generally tend to be less stringent than in Europe. Some Asian countries may not have specific regulations in place to protect passengers in the event of delays, so it is often up to the airline's policy. It is important for passengers to review the conditions of carriage outlined by the airline when traveling in or through Asia.
