One of the best bits of customer-first attitude I ever saw in the industry took place aboard a VLM F50.
We were all sat aboard on the London City ramp ready to depart for Manchester. Skipper came on the PA to say there were still a few minutes before departure time and we were "waiting for a connecting passenger". Sure enough another VLM F50, inbound from Antwerp and a bit late, taxied in to the adjacent stand and our dispatcher was waiting by their steps. Out get pax #1 and the DS speaks to him and takes him towards us.
Guess what, he had hold baggage. Ramper opens hold, pax identifies his bag, DS takes it, puts pax up our stairs and bag in our hold. Completes load sheet, and we are closed up and away on time.
Poor travel-weary pax in his dishevelled suit (appeared to be Spanish as his newspaper he was reading was in that language) collapses in our plane and sleeps the trip up to Manchester.
Now KLM, can you match that ? The whole thing had presumably been coordinated on the company frequency in the minutes beforehand. VLM got to where they are by knowing the business traveller world inside-out and working in this and similar ways.
