That's one thing - but not the only thing.
I flew BA a couple of weeks ago. Got a sandwich in a plastic wrapper. a ba.com paper cup, and on way home had a G&T served in plastic cup.
Flew VLM to AMS last week. Cabin interior far better than BA's tired old 146s, VLM have these smart new tan leather reclining seats. More inch leg room. Catering served on a tray including a yoghurt and fruit. Yes, coffee in a proper cup, and Bar service uses propper glasses.
And a real nice touch - basket of sweets served as aircraft door is closed, and the crew member at the front asked if they could take my suit jacket and hung it in the wardrobe at front of cabin.
I noticed VLM won Best Regional Airline Europe and Best Cabin Crew Western Europe in September's Skytrax awards. Personally - I can see why.
In no way am I saying BA are bad, but I personally feel that at the moment VLM are better, plus they have a high frequency on LCY AMS.
