In the past 5 months the missus and I have done a bunch of traveling. My typical "non-photography" kit for when I'm the only person in the group shooting with anything other than an iPhone

is a Sony body, 20-70 F4 and either a Leica Q or 35 1.4 GM along with about 4 spare batteries.
Sometimes will take the 70-200 2.8 MKII but not often.
We've been through security at SEA, IST, HAN, SGN, PNH, HNL, ATH, DUB, ICN and probably a few more I'm forgetting.
Zero issues. I take the iPad and the body+20-70mm lens out and leave the rest in the bag.
