Yeah, they were going from Toronto to Germany through Iceland. Their plane was an hour late leaving because the conveyor for putting luggage onto the plane wasn't working (apparently a common issue right now with not enough maintenance people). Her husband's bag didn't make it onto the plane in Iceland (hers and her kids' did) though all luggage made it TO Iceland. So his bag was sent to Munich a day late,r but when he went to try to pick it up at the airport on their way to Stuttgart, he couldn't track down anyone who would go find it. Apparently, there were other people there who had been at the airport every day for four days trying to get their luggage. So they had the bag sent back to Toronto since they were going to be ending up in Switzerland. The bag has been at Pearson since December 28th, and they returned to Toronto on January 8th. She can see it moving from place to place at Pearson (Air tags) but is still waiting. Everybody I know who has been through Pearson says that there are piles of luggage everywhere and nothing seems to be happening with them. But I also know other people who have flown in and out of Toronto, and everything was fine. Personally, I'm not taking any chances.
We're only going for a few days and will spend most of our time at the pool and casually dressed, so it's feasible, but it's also required a lot of hard decisions, pruning of items, selecting lightweight everything, making sure my colours mix and match, and wearing a fleece and rain jacket instead of packing a sweater and/or wearing winter clothing to travel. And keeping my toiletries to a minimum. Nothing that isn't actually needed - no nice-to-haves or maybe-usefuls to be packed.
You may be fine, but if you still need to take a suitcase, you might want to consider splitting everything into two smaller suitcases and dividing everything up so that you might at least get one and there will be enough to not need to buy anything. But definitely put as much as you can/need into the carry-on bags (something I always do anyway), just in case. Between the airlines and the airports, it's a you-know-what show right now with travelling.
