Flights between Heathrow and Brussels: what a delay is worth
Leaving Heathrow
£220 per passenger, UK261
Leaving Brussels
€250 per passenger, EU261
Brussels is in the EU, so this applies whichever airline you fly.
Either figure is payable only when the delay was within the airline's control. A technical fault, a crew shortage or a late inbound aircraft all count; genuinely extraordinary circumstances such as severe weather or an air traffic control restriction do not.
Heathrow and Brussels are 350 km apart (1,500 km or less), and that distance is all that decides the amount. Which figure applies depends only on which end of the route you departed from, not which way you were travelling.
In the last 12 months, 4,723 flights operated between Heathrow and Brussels, and 0.2% were 3 or more hours late, the threshold where £220 per passenger becomes payable under UK261 (€250 under EU261).
Punctuality is down on last year: 67.9% of flights ran on time against 68.4% in the twelve months before, and the average delay rose from 13.9 to 14.9 minutes.

The CAA's figures don't separate arrivals from departures, so this covers the route both ways.

Your rights on this route
Every flight leaving Heathrow for Brussels is covered by UK261, whichever airline operates it. Flights the other way, leaving Brussels for Heathrow, are covered too if a UK or EU airline operated them; a flight that way on a non-UK, non-EU carrier falls outside UK261, though the Montreal Convention may still give you a claim. See the full breakdown on the 3-hour rule. Cancelled instead of delayed? Broadly the same amounts apply under different conditions. See cancelled flight compensation.
