The first spoiler of a season is always what gets me jumpy and breathless! You guys are great!
Hmm, a 7/4 split for the first flight?
The Portland > Frankfurt plane is simply the reverse of TAR 13's final flight, isn't it? That's LH469, departing at 1.35pm to 9.05am the next day, a flight duration of 10h 30min. Portland, Maine doesn't have a direct flight to Frankfurt - and it'd take a much shorter time too if it did!
Only Lufthansa and Swiss Air for the Frankfurt > Zurich leg, and it looks like they're running codeshare. Here're the possible options:
And... There're plenty of trains (departure times differ by less than an hour) from Zurich Airport to Locarno, taking a little over 3 hours with a couple of connections. They'd be able to make it there the same day, albeit in the afternoon. First one gets them in at 1606, provided they can hop on by 1147.
Frankfurt is the airport serving the most destinations worldwide. Not much hope of finding where they start, eh? But if we assume it's straight from the US to Frankfurt, we have the following 21 cities as candidates, with all flights getting in before noon:
The good news? Looks like the LA flight gets in too late for the racers to be lounging around before Matty gets to Frankfurt!
