Flight reservations are essentially a temporary booking of a flight seat without actually purchasing the ticket. Here are some of the limits of flight reservations:
Duration: Flight reservations are typically valid for a limited period, usually ranging from a few hours to a few days. The duration of the reservation can vary depending on the airline or booking website.
Payment: Flight reservations do not require payment upfront, and you are not guaranteed a seat on the flight until you purchase the ticket. You may be required to pay a deposit to secure your reservation or provide your credit card details as a guarantee, but you will not be charged until you confirm and purchase the ticket.
Availability: Flight reservations do not guarantee availability of seats on the flight. Even if you have a reservation, the airline may sell out of seats before you purchase the ticket, or the flight may be cancelled or rescheduled.
Visa application: Flight reservations are often used as proof of onward travel for visa applications, but some countries may not accept them. It's always important to check the visa requirements of the country you plan to visit and ensure that you have the appropriate documentation.
Change and cancellation fees: If you need to make changes or cancel your flight reservation, you may be subject to fees, depending on the airline or booking website's policies. Some airlines may also not allow changes or cancellations for certain types of reservations, such as discounted or promotional fares.
