Hi,
I see If you go for a flexable ticket you can pay 5-10X more of the cost of a normal fair.
I see the change fee's for normal fares are about 200usd change fee.
As you need to pay the fair difference on both ticket types would would anyone ever get a flex for that amount more when they can go for a basic and just stump the fee?
Sorry If I have miss-understood.
Regional.
