Just depends on who you get. I was in the IAH Term B club this past weekend and asked the club agent to change my return from JAX from the 5:-- to the 3:-- on Friday, as the website threw up the "technical problems" message.

Anyway, the website gave me a price of $150 to change with no fare differential, where this is before it below the error message. However, when the club agent did it, he literally tapped away at the keys for about 15 seconds and then came back with a fee of $700 to change the flight. 15 seconds doesn't pass my smell test, but I digress.

Of course, he politely declined for me on the change as he thought it outrageous, of which I agreed with him on. I then went to my normal cubicle there and called the Plat Elite Line and they were able to consumate it for the $150 without me ever mentioning what had happened with the club agent.

What this goes to show you is that it all depends upon the agent you get, and if you get an unexpected answer, just try again.
