Thanks a lot for the upgraded tool; love it a lot!!!
There are two bugs I've found so far:
Firstly, take a look at the discrepancy between what ITA shows me and AC.
Adding the real flight time to the one shown on AC (German edition btw, but also happens on Canadian one) followed by subtracting it from the arrival and departure times on the AC site gives you the ITA data - eg 14:10-(1:25+6:35)=6:10. However, what surprises me is that on FRA-VIE the aircraft doesn't match up (321 on ITA vs 32A on AC). On Monday LH1238 indeed is a 32A, so obviously the date is passed incorrectly to AC.
LH and AA work fine.
Secondly, I'm not able to change the number of passengers. Using one pax on ITA, changing it to two at the top of the script (pax management) or using two on ITA and changing it to two in the script will still be shown as one passenger on either LH, AC, AA or FareFreaks.
