Your use of frog makes me want to puke!!!
Charming!
LF does not need it for any of the routes that it flies the aircraft on
I didn't know that Norwegian.se had the 747-8i. I trust the rest of your research on the -8i is more accurate than that for the ICAO code for Lufthansa.
The production rate for the similarly sized A330 is running at about 9 per month, albeit after a significant time in service. What's the production rate of the 747-8, a similar sized aircraft to the A380? About 2 a month is the number I've read. Pommes avec des pommes ou des pommes avec des oranges?
