Looking at the flight schedule it seems the MXP flights will be operated by Italian-based machines - dep MXP 0715, arr BRS 0825, dep BRS 0850, arr MXP 1155, slightly different timings at weekends (all times local).
A tad early as a departure from MXP if you're doing a quick break but easier than flying into Pisa and out of Venice or Rome with TrenItalia filling in the missing bits. Milan's well worth a visit and the route's a welcome addition to the EZY route network at BRS. BA to MXP was never "cheap" when looking 3/4 weeks ahead to book a flight.
