Thanks WX man, kind of you to ask. These would be my suggested guidelines...
- Smile back when smiled at...
- Make eye contact when speaking to us or vice versa...
- Acknowledge and respond with basic courtesies (Hello, Goodbye, Please, Thank-you etc.)
- A lightness of manner and a sense of humour make life more pleasant for all involved
In short, treat Cabin Crew with the same courtesy and respect with which you would wish to be treated yourself.
While I'm at it, a word about what to do when you are dissatisfied! When things go wrong, it is a little pointless letting rip at people who have no responsibility for the problem, or who are unable to influence the outcome of events in any way. Abusing or berating cabin crew for aircraft technical delays, lost baggage or seat pitch is unproductive for you and demoralising for us and can achieve nothing except to generate bad humour all round. These are all matters appropriate for communication with the Customer Relations department. If the problem lies with an individual crew member's behaviour or attitude, the the senior cabin crew member is the person to talk to (note:
talk not yell). In this way, seniors may be able more easily to spot those who are persistently involved in complaints. These methods of complaining are true for airlines, supermarkets, call centres and just about every industry you can think of: target complaints at those who are responsible or who have authority, not those who have neither. Abusing the powerless is bullying, pure and simple.
I hope this answers your question, although the very fact that you ask it probably means that you are a "good" passenger in the first place - therefore I hope to fly with you.
