Yesterday I went for a day business trip from BRU(ssels) to MAN(chester) and back on Brussels Airlines in b.light. Everything worked out fine (reservation, online check-in, boarding, flight, service with a smile, on-time performance, etc.), with one funny exception.
When checking in on Internet the day before the flight (on an Avro RJ85)the computer had assigned me seat 18F. Since I did not have Flash Player 7 to change seats, I accepted and printed the boarding pass. During boarding, the gate agent first accepted my pass, then called me back and said there was a change of seats. He re-assigned me to seat 16A. I was lucky: row 16 is the last full row in the Avro 85. Row 17 has only seats A and C, and there is now row 18! I could have ended up standing for the whole flight
The load factor was around 50%, which means there was no problem to get me a free seat, and even a whole free row.
