Whether or not
plane tickets are refundable depends on the type of ticket you purchase and the airline's refund policy.
In general, most airlines offer two types of tickets: refundable and non-refundable. Refundable tickets are typically more expensive than non-refundable tickets, but they allow you to cancel your reservation and receive a full refund, or a partial refund depending on the airline's policies, up to a certain deadline before your flight.
Non-refundable tickets, on the other hand, are generally cheaper than refundable tickets but do not allow you to cancel your reservation and receive a refund. However, many airlines do allow you to make changes to your reservation, such as changing the dates or times of your flight, for a fee.
It's important to note that even if you purchase a refundable ticket, there may be certain conditions that apply to receive a refund, such as a deadline for cancellation or fees for making changes to your reservation.
It's always a good idea to read the terms and conditions of your ticket carefully before purchasing and to check the airline's refund policy to understand your options if you need to cancel or change your reservation.
