I got to sample Band 4 breakfast on Wednesday 12 September, flying LHR-CHQ. I was very happy that a lighter breakfast option - smoked salmon - had been introduced, as I had just stuffed myself in the CX F lounge at T3. The service was very good, with tea/coffee/champagne/water being proactively topped up throughout the flight.
As someone had mentioned before, ice is no longer proactively offered (and this time around lemon wasn't either). I didn't ask for it, but I assumed it would have been available.
The new mug isn't in the photos, but I very much liked the design.
