I like the new livery on their planes. How long have they had that for??
Much better than the old drab conservative British Airways..

Interesting about the frozen fuel. I thought that aircraft had tank
heaters. Maybe not?

Frozen fuel? I can't see any mention.

The AAIB bulletin

http://www.aaib.gov.uk/cms_resources/S3-2008%%20G-YMMM.pdf

indicated that the fuel temperatures never got low enough by a
considerable margin, and even the lowest total air temperature of -45C
was higher than the specified maximum freezing point of -47C for Jet
A-1, and was significantly higher than the measured freezing point of
the fuel remaining in the aircraft, being -57C.

There are no fuel heaters!

Once fuel temperatures become critical, the aircraft must descend to
warmer air and/or increase airspeed to raise the total temperaure.

The alternatives seem to be

a) Let the fuel freeze.
