Can charter travel tickets be refunded?

There are indeed many regulations on group air tickets of travel companies. The air ticket fees may not be refundable, but at least there are fuel taxes and airport construction fees that can be refunded.

The preferential group prices for air tickets booked by tour groups are often accompanied by strict restrictions on use. Tour operators should provide tourists with written information such as the "Itinerary" issued by the airline that contains the restricted use conditions of the ticket. If the restricted use conditions of the ticket clearly stipulate that the ticket is non-refundable, then there is no way. You can ask the travel company for the airline you are traveling with, and call the airline to confirm whether the ticket is non-refundable.
