I was scheduled to fly BRU-PHL on US715 today (in Y), and then on to RSW on US1167. Due to an aircraft problem in BRU (they had to defuel the plane, replace a piece, refuel again) the flight BRU-PHL was delayed more than 5 hours, causing me to miss my connecting flight in PHL.
Still at BRU airport, I called US and asked what my options for a later connection to RSW would be. They said, all planes today were full, so I would have to stay overnight in PHL, or possibly take a 3 segments flight, which would have also caused me to arrive in RSW on the next day.
So, I opted to wait in BRU until tomorrow and stick to my itinerary as planned, only do it 24h later.

I wonder what compensation I can expect for this cock-up. Also, do you have any advice how should I go about requesting a compensation?

Thanks for your advice.
