# Obtaining A Quote for Flight Change

When you reschedule a flight voluntarily, the total cost is made up of two parts:

1. **Rescheduling Rules (set by the airline)** 
2. **Fare Difference (between your original flight and the new one)** 

Follow the steps below to check both in ATRIP. 

#### Step 1: Check Rescheduling Rules 

* Go to **ATRIP → Bookings → My Bookings → Booking Details → Booking Info** 
* Review the airline’s rules for flight change (e.g., change fees, conditions). Click "View" to see the corresponding Fare Rules.

#### Step 2: Check the Price Difference

* Go to **ATRIP → Fare Search**.
* Search for the new flight you wish to take. 
* Compare the new fare with the original booking fare. 
* The difference between the two is the possible flight change cost.
