I need to fly back home from a non-Schengen country this fall (a Wednesday in early October) to avoid the risk of overstaying the 90-day limit by testing positive in Italy near the end of a trip that would otherwise end in Venice. My solution is to return from Zagreb. If I test positive in Croatia, I'll be able to stick around as long as I need to without exceeding 90 Schengen days.
There are a lot of United frequent-flyer options with very similar costs in terms of miles and taxes. My problem is balancing transfer risk against my hatred of early wake-up calls. I don't mind rather long layovers on the way home; it's just that they're usually accompanied by terribly early departure times. In this case I'm worried about two additional factors: The on-going bottlenecks at multiple potential transfer points that are redefining what constitutes a "risky" transfer time, and my need to avoid getting stuck for too long at a transfer point in a Schengen country. Things could get dicey if I get hung up for multiple days at a Schengen airport that is experiencing a meltdown.
These first two options have semi-acceptable departure time, but the connections feel risky. However, I know nothing about the connection situation in Zurich and Vienna. What say those of you familiar with those airports?
9:15 AM: changing planes in Zurich (1 hr 10 min). I'd love this, but that connection time seems insane to me. If I don't make the connection in Zurich, there's not another non-stop, and I might end up on a later flight with a 1 hr 30 min transfer in Frankfurt, which I bet is more problematic than 1 hr 10 min in Zurich.
8:15 AM: changing planes in Vienna (1 hr 45 min). Departs earlier than I'd like, but I'd be tempted if this is a decent time allowance in Vienna. There are no later non-stops from Vienna, so if I missed the connection, I'd be changing planes at Heathrow (2 hr 20 min--seems short there), Munich (2 hr 20 min--maybe OK?) or Frankfurt (1 hr 35 min--seems too short right now).
If, as I fear, those are not good choices, I think I'm stuck with transferring in Frankfurt. I'd rather avoid it, given current conditions, but at least it has multiple daily non-stops to IAD:
9:15 AM: changing planes in Frankfurt (2 hr 30 min). In previous years I'd have been quite happy to book this, but I gather it's not a good idea these days. Missing this connection would mean a 4-hour-later flight to IAD, but it would be a non-stop.
There's an earlier departure through Frankfurt with more breathing room than the 9:15 AM flight has. Do I need to go with it?
7:45 AM: changing planes in Frankfurt (layover of either 3 hr 5 min or 3 hr 55 min). There's that later non-stop out of Frankfurt if I missed either of these connections.
What would you do?
