Hello all, I've been searching here, asked "Alex" and Carpe Google'd and am not finding a "for sure" answer (Maybe my search skills need improving but I digress...).

What is the lowest fare class that allows "no fee" changes in coach for int'l travel? Is it Y H M? I do not mean same day changes, but changes in advance.

I need to book a ticket for some people to fly US/Europe staying a few months then returning. I am fairly sure that the return date will change a few a few times.

I often change flights but am in F/Y full fare, either expense it or am on reward tx allowing free changes anyway thus I am not familar with the classes. Everything I find online talks about earning miles but not fees.Thanks for any help.

Ciao,
FH
