Virgin wanted £25 per person per flight when we went last year, so it would've been £200 on top of the flight price to prebook seats.
No way was I paying that. I checked in online exactly 24 hours before we flew, the earliest that I could, and we'd been allocated 2x 2 seats together with a few rows between but I managed to change it so that we were seated two seats behind the other two which is exactly what I'd have been booking had I paid to prebook. Coming back we'd been allocated three together with one across the aisle which was fine.
Oh, and when I checked seating a few days before we flew the price to prebook had increased to £30 so it would then have cost £240.
