How can I change my flight to a later time

Which airline are you flying? Most are very helpful but I've found its best to ask for pricing for any changes. I wasn't told about a $200 change until I was charged after the call.

If at the airport go to the airline check in. Otherwise call

Call the airline. If you are already at the airport, most of the airlines have an information desk where you can ask to make changes. However, most tickets do not give you the option to change for free, you might have to pay a fee.

yes call the airline

Call the airline
