I am sure that the flight is operating with a B772 as it usually does. Just one of those pesky glitches. EGLL to KIAH is about 4200 miles. Even a 737-900ER only has about 3200 miles of range.
What confused everybody was “CAL”, as you’ve realized. As far as flights go, they’ll go off the ICAO code for the airline. In this case, Continental’s code is COA. CAL is actually China Airlines.
It’s a B772, I’ve flown this many times (including when it was out of EGKK). It’s an issue with our UK tracking due to the fact that we’re using US flight tracking data to figure out the aircraft type. Known bug that’ll be fixed.
You said it, brother!
You said it so compactly that it took me a min to figure out you were continuing the thread. I still think I missed about half of the info you gave.
