Seems I overlooked the small detail I was re-booking myself to Linate instead of Malpensa in the course of a BA schedule change.
Currently now booked on BA0572 LHR - LIN on a Thursday morning in November, dep 07.35 h, arr. 10.35 h.
Need to catch Qatar same afternoon at 15.10 h from MXP to CPT via DOH.
First LHR - MXP flight doesn't arrive until 14.40 h, so not an option.
Question for those of you familiar with Milan airports: with 4 1/2 half hours between flights, should I catch a transfer from LIN to MXP on the same day? If so, bus, train, or ...?
Or should I go the day before and just spend the night in Milan?

Any comments greatly appreciated as Milan is one of the places I am not familiar with.
