Thought that would get a response!
I knew the 400 would provide a similar blox time. Wasnt sure about the 300 When I used to give a **** and was an aviation nerd I could probably have told you what sort of equipment was used on that route and whether there was a codeshare or not.
Now that years in aviation has crushed my spirit I merely engage in idle speculation. I can't even be bothered to open a web page to check this sort of info these days.
