What are some air travel items that are indispensable to you?
For me, it's the following:
1. TSA PreCheck - worth it when the security line is backed up.
2. Wilderness Frequent Flier Belt - Any non-metallic belt, but I like this one.
3. A hat or hoodie - I hate letting my bare head touch airplane headrests.
4. Shirt with chest pocket(s) - it's a pain dealing with pants pockets when sitting on a plane. Any things that are in my pockets get transferred to this temporarily. Boarding pass, phone, earbuds.
5. Long pants and long-sleeve shirt - See #3 for my personal phobias.
6. Apple Airpods Pro - Just got mine before my last trip and they are a game changer to someone who has used traditional, wired, non-noise cancelling earbuds/headphones for years. The ability to switch between noise cancellation and "hear-through" mode with a simple long press is so convenient.
7. Anker Powercore Fusion - combination USB charger and power bank. I used to carry two Apple USB wall warts and a backup battery. This replaces them all. I only wish it supported USB-C fast charging.
