Best viewed in context of dismal reality of standard contact options for BA - apart perhaps from GGLs.

First, one has some hope the call will be answered swiftly;
Second, friendly, approachable and reassuring (OP rather unlucky);
Third, proactive (offered to rebook if was in danger of missing 1 hour check in limit before an AVIOS redemption flight);
Fourth, flexible (offered multiple options to change a Club return leg (First out) where BA had moved departure forward an hour).

Menu in advance unreliable, although did receive a profuse apology after flight.. A very pleasant chocolate teapot.

It may be that all above should be available to all but, until then, one certainly feels first amongst equals...
