Stocked with sufficient avios earned on a Qatar Airways business class return from Budapest to Chaing Mai, we've booked ourselves some returns from Rotterdam Airport to London City Airport. It's ultra-short-haul, taking just over 30 minutes under optimal circumstances. It's a worthwhile redemption, you spend some 9,000 Avios on a return plus 44 euros in taxes. Given it's a business route, it can be rather costly if you have to pay for the flight in cash. In this case, I think it was some 275 euro at the time of booking.
Anyway, we had already been pleasantly surprised on a RTM-LCY leg with BA CityFlyer, but this time it was a nice flight as well. It's definitely more relaxed flying between two such small airports. The amazing thing is that the stewards/stewardesses (they're called customer service managers in this case, really) are very friendly and make the best of the 30 minutes in the air. They even get you something to drink and to eat, for free!
Yes, after all the complaining on BA becoming a low cost carrier, its regional sibling CityFlyer maintains free catering (the flight's too short for payments anyway), has considerable legroom in their Embraer jets and overall gives you the impression that the people working there are still enjoying their jobs. Recommended!
