No, it's not at all new, at least not since carrier surcharges were removed from shorthaul services. The cheaper the ticket the more you get back. I had one ex Porto cancellation, where the fare was 2€, and so that was my entire loss when I shifted the flight to another date. The £60 change fee is normal, rising to £100 /130€ for I class CE fares. Due to sterling's volatility, the actual change cost can currently be lower than this if taxes are shown to have reduced, and it's a return leg.

G fares - for weekend same day tickets, are often cheaper than O.
