I think you’re confusing Worldwide Cabin Crew (WW) with Mixed Fleet (MF).

Customer Service Leaders (CSLs) are as CIHY said former Pursers. They generally lead a team in a particular cabin such as First and work as Worldwide Cabin Crew. They are more senior than regular cabin crew (‘main crew’) but below the Cabin Service Director (CSD). So, on a Worldwide crewed flight there will be

1 x Cabin Service Director (silver tie) - in overall charge of service throughout aircraft. They will also generally be in charge of the Club World cabin (it’s a bit different on the A380).

1 or 2 x Customer Service Leader (normal uniform) - in charge of service in a particular cabin - so if no F cabin there will only be 1 CSL, in charge of WT and WT+ with CSD in charge in Club. You may sometimes get 2 though (if crew are, say, operating a 3 cabin aircraft one way and 4 cabin aircraft the other and sometimes CSLs may be rostered but working down as main crew). On the A380, I believe there is a CSL on the main deck and a CSL on the upper deck, rather than specific to each cabin. CSLs can work up as in charge crew member if, say, the CSD falls ill.

WW female crew do not wear hats, except on A380s and 787 when they do...or if they are Ambassador crew performing Ambassador duties.

There is no recruitment or promotion on WW any more. I don’t know whether it’s still possible to transfer from Eurofleet to Worldwide and vice versa.

On Mixed Fleet (MF), the most senior crew member is the Customer Service Manager (CSM) - silver tie.

MF also have ‘World Class’ cabin crew (WCC) who are on CSM development. In addition to standing in when CSM is unwell downroute, they have to carry out a certain number of flights where they work up as CSM under assessment. To try to get a spread of experience, the WCC will often ‘lead’ a particular cabin. I think they wear a normal uniform and have never seen a name badge with ‘World Class’ on, so guess they just wear a standard name badge - ie you would have no way of knowing they are senior crew.

You might also see an Inflight Business Manager (IBM). They are common to WW and MF and line manage CSDs and CSMs (I don’t know whether although the title is common they work across WW and MF - would be odd as many CSDs have 20+ years’ service whereas CSMs can be direct entry and could apply for IBM as next step). They’re not on many flights but do fly from time to time - I guess performing appraisals on the CSD / CSM.

You then have International Cabin Crew (ICC) - generally only 1 level but there is a more senior IBM-type level so will occasionally see a crew in normal ICC uniform but wearing a badge saying ‘Senior Cabin Crew’.

Female MF crew wear hats and uniform is to ‘Ambassador standard’ which in practical terms affects the way cravats should be worn....yes, really!

Then, finally, there’s Eurofleet (EF).

They have Pursers (silver tie) and Main Crew. You generally have 1 purser on a flight but it’s relatively common to see multiple Pursers working down as there are too many as MF expands - BA acquired a lot of senior crew who TUPEd over on acquiring BMI.

There used to be Cabin Service Directors on EF who operated Airbus (instead of a Purser) but only CSDs could operate Boeing 757 / 767 flights due to union agreements. Obviously the 757 / 767 have now been retired. I had understood EF CSDs would be going too, but not sure if this has happened.

EF crew do not wear hats.

Gatwick is now CSM and CC but new recruits fly with experienced crew there.

The crazy thing about all of this is that MF and WW / EF don’t fly together. I’m sure all could learn from one another.

All of this is my understanding so stand to be corrected!

75 min slot delay yesterdaay on LUX-LHR flight perfect opportunity to use it, curtain pulled and crew not seen until safety demo time.

If you are not fussed, why is it you find it annoying? It’s nice to receive a welcome, but when I don’t receive a formal one it doesn’t even cross my mind. Whilst I often have Premium Services contact from AA at their hubs, I cannot remember the last time I received any form of recognition on board - it must be at least 6 or 7 years.

Yes, full credit to her for the greeting and for trying (even if no posh pillows / blankets available)

Perhaps the CSM didn’t expect you to actually take up the offer, and your request threw her ?

Bit like saying to the mother-in-law (just as she’s leaving after a weekend stay .....) “No, no ..... we always love having you to stay ..... do come again whenever you want ....”

Looks like we were on the same flight. We got welcomed too in ET. Was a long time ago for us in ET when it last happened. He told the lady behind us something like ‘I have a message from the Excecutive Club for you. They missed you, well they miss your money I suppose. Welcome back’. Sounds a bit weird for me. But ok.
