Hi guys,

In the Premium fare forums, I've noticed that there are a lot of good fares that are, understandably, restricted to certain travel periods, min/max stay etc.

So, say that an example fare condition is that travel is between Jan-March 2015, max stay is 2 month. I book the fare under these conditions, flying late Jan returning in Feb.

However, say I didn't want to fly back in February and wanted to fly back in April. What would the cost of the date change involve? I know it would be fee + fare difference, but I'm really confused as to whether this be a minimal, moderate or costly figure.

What really puts me off is the range of prices in J. In Y, I could understand if it was between $100-$600, but in J, is it a similar ballpark or is it more like $100-$6000?

Any clarity would be much appreciated.
