A few that stick in my mind
Bahrein to Amsterdam in mid 70s on KLM DC8 -30 three pax , me 23 and two very elderly gentlemen . A very attentive cabin crew who also invited me to a birthday party for one of them during the overnight stay in AMS
Seychelles to Mauritus 1980 ish . BA 747 ex BAh arrives in Seychelles but cannot leave becuase en route bird strike knackered on engine , no spares, thunderstorm, apartheid routings delay flight for 72 hours
LHR-Abu Dhabi Gulf air 1011 , Three hours in cabin crew member comes and asks my name -on confirming she says please come to the flight deck as you have a 'phone' call , Amused flight crew explain it is my wife who is duty Speedbird London radio operator havign her little joke
Stockholm ARN to Berlin Templehoff in 1992 F27 this time only 2 pax , one sat at back and me right at front peering through open cockpit door. Cheery LH FO says why not come and sit up here if you are so interested so jump seated the whole rest of way
LHR-MIA seated next to heavy crew FO who very chatty, when his turn up front asks Captain if I can join so many hours up front in the bizarrely tiny flight deck of the mighty 74 . v interesting seeing other a/c in midst of now where including several headed east under the westbound tracks
LGW-BDA depart LGW on time at 1420 never leave UK airspace inumberable orbits over Lands End and return to Gatwick at 2015 date Sept 11 2001 .
Nothing v exceptional since those days altho I was immensely impressed with QR business class on A380 earlier this year
