Alitalia MilleMiglia - Can I change my ticket after a small schedule change?

I have a ticket of AZ494 from FCO to OTP next monday. I was notified that the flight has been changed from 14:25 to 14:40. This is not a surprise -- I booked the flight a year ago.

However if they allow me to change my ticket, I want to change it to another date. Has anyone worked with alitalia with this kind of cases? It's a class Q ticket so I don't think I can change it for free, but what about with a schedule change?

It's 15 minutes change... Save your time.
If it was 2+ hours they would change it, but 15 minutes is pretty much the same

Q sounds like quite low down the scale. Don't expect any change of rules for 15 minutes, so you're gonna have to pay the 50EUR+fare difference (unless negative) to change date.

It doesn't hurt to ask though. I think the odds are against you, but I have had luck changing the date on an AA ticket with a 20 minute change. AA is generally very accommodating on such changes though.
