Yes..I have even managed to get a £9.99 chargeback via Amex after flybe collapsed..
For those confused about chargeback.and section 75 this is a very good article.

I had 4 tickets on easyjet for the next 10 days and easyjet were refusing refunds.
So did a dispute via AMEX . Got my charges reversed for all 4 tickets and now my Amex balance statement is negative
