I am traveling soon and feel like it would be easy to bring 2 liquid 3 oz bags in 2 separate bags. Has anyone tried that?

Online I keep seeing 1 liquid bag per passenger, which they’re scanning those bags one by one are they tying each bag to their passenger? And in some places I see it’s 1 liquid bag per bag. So I’m confused.

Man, I'm stumped. This should be easy! I'm going to be traveling (by plane) in such a way that I won't have time to stop for food for about 6 hours, then once I land, I likely won't have access to food for another couple of hours, so I'm looking for travel-able food/snack ideas.

What are some good, filling (preferably protein-based or protein-heavy) snacks to bring on a plane that aren't nuts?

Are we still allowed to bring homemade food like sandwiches?

Also, I'm crossing the Canadian border by plane so will I have to "declare" food items when I get there?

TIA for ideas!

I'm putting together a multi city Europe trip and can't decide if I should book every train before I leave or keep things flexible. I like having room to change plans but I also don't want to get stuck paying double because I waited too long. The rough plan is Paris, Rotterdam, Amsterdam, then London over about two weeks. If you've done something like this before, how did your trip go? Any advice?

The insurance I'm looking at (American Express) lets me build my own plan, I want medical expenses only. But coverage is only good for 60 days and it would be fraudulent to take a second policy for the remaining 60 days because I won't be departing from my residence. I'll already be there. This would be true for any insurance, I'm assuming. I'll be in one European country, in only two locations, working, doing nothing "dangerous". I have a European passport (not of the country I'll be in) as well, and this is the first time I'm getting travel insurance. I've never worried about it in the past. Any other "create your own plan" providers that would cover the 4 months? I don't want to be forced to pay for coverage I don't want. Thanks so much! [edit for punctuation]
