Are you holding airline tickets for an upcoming trip? The odds are favorable that you will fly on schedule.

But as air travel ramps back up, be aware that the airlines have been tweaking departure times, flight frequency, and in some cases even swapping aircraft models based on customer demand — or lack thereof.

You can get an idea of the many changes taking place in air travel right now by doing a quick Google Flights search for one-way travel between certain cities.

If you're trying to take advantage of an airfare deal for a trip that's months away, there's a good chance the flight you book will change between now and then — certainly if demand for consumer travel stays flat and the airlines continue to adjust routes for their profitability.

The airlines are required to notify you of major flight schedule changes, but there are times when a notification just doesn't get sent.

So it's essential for you to keep a close eye on your itinerary.

Some travelers are reporting that the new re-booked flight times are terribly inconvenient. As a consumer, you do not have to accept the rescheduled itinerary if it doesn't suit you.

According to the U.S. Department of Transportation (DOT), customers are “entitled to a refund regardless of the reason” if the booked flight is canceled by the airline.

If the airline puts you on a schedule that requires a connection when you originally booked a nonstop flight, you can get a full refund. And if the new flight is more than two hours delayed from the original departure time and you are unhappy with the new schedule, you are also entitled to a refund.
