- If at all possible, avoid checked luggage - it's overpriced, slow and unreliable. No news to pro travellers I guess
- Luggage reimbursement is capped at a relatively low figure that hasn't increased in decades (sources vary, jurisdiction unclear when international which just adds to the point). In any case, if you're traveling with a fancy Rimowa, the luggage itself is worth that... Never put valuables in checked luggage
- The whole process seems increasingly stupid to me. A lot of conveyor belts, tracking systems etc. just to get a bag that I can carry by my own, all because the space in the overhead compartments is limited - manufacturers are working on larger compartments recently
- Some airlines are nearly impossible to contact - you might be asked to call a number in <random country> and then wait in line for 2, 3 hours then the call drops randomly (looking at you, Aegean)
- I appreciate this might be unavoidable for families, i.e. when you carry luggage for multiple people, or when you need a set of suits etc. But still, keep the Rolex on your wrist
