I was booked on BA942 LHR - DUS on Sun 6 Apr, the day it snowed! The flight was inevitably cancelled, and I have to say that T5 seemed a pit of misery and despair to me and others. I had to get to Germany for a military appointment, and being forewarned about T5 I'd booked my suitcase into left luggage and took only hand baggage.
The positive - the BA staff (there seemed to be loads of them wearing T shirts saying "can I help?") were unfailingly polite and patient. One chap spent about 35 - 40 mins persuading and cajoling others to get me onto the BA940, which had been delayed, even though the gate had been closed for some time. I eventually got to DUS on BA940 about 2 hours after my planned arrival. I didn't catch the fella's name, but he was ex-RAF BA flight crew.
I just wanted to thanks, whoever you are, it was appreciated.
