Trip report, tldr: we made it but not without some shenanigans. Well worth it for just over a month on the ground in Croatia and Slovenia.
On the way out, we first delayed a day due to absolute horrific loads and desiring a little more time to get ready. Next day, got C+ seats to JFK and JFK-CDG was looking good that night with a backup or two in hand. Boarded up in DEN, pushed back and we sat. And sat. Great. Sure enough, left engine wasn't happy after startup so back to the gate we went.
Since we committed the non-rev sin of checking a bag, sadly we couldn't quite be our normal flexible selves. JetBlue had a flight we could have made but the checked bag of course sunk us. So we hung out while the delay dragged on. Eventually said screw it, let's go home and try again another day. Went and had a surprisingly not overpriced beer at the Westin bar while we waited for our bag to make it back to baggage claim. Good news was, we now had more time to fine tune our pack job and snuggle the cats.
Our next attempt was DEN-MSP-AMS, but MSP-AMS went from 11 open in D1 to 0 within 18 hours. Just...how? Ended up DEN-DTW-CDG and again had a decent shot at D1 but once again got skunked. C'est la vie. So we lived our best lives in row 55 to Paris but at least we had the middle row to ourselves and the FAs kept our steerage swill nicely topped off.
After a fun night in Paris we hopped on Croatia Air and as usual purchased some treats for the crew. The lead FA was super nice and put us in the empty biz section and hooked us up with plenty of bubbly and snacks on our way to Split.
On the return, the loads out of Ljubljana weren't great as we failed to realize there was a marathon that final weekend of our journey. So LJU-ZRH-AMS. Also Swiss/Baltic are super uhhh...'Swiss' on bag size and restrictions. Usually for non-revs it's not a problem but they made us pay an extra $90 CHF for the extra bag to ZRH. KLM to AMS? No worries of course.
Then out of AMS our first choice was to MSP on a Trash Panda with plenty of D1 suites available. So of course that went on a rolling delay with some sort of issue up front. At this point, we'd had enough travel shenangigans and just wanted to get home. Gave up on that and quickly changed our listing to DTW, finally got some D1 action and made it home.
Probably the most interesting non-rev experience we've had in a few years but sometimes that's the way the cookie crumbles.
