I read an article the other day that some airlines are limiting it to one lithium ion battery and you have to keep the battery easily accessible, not in the overhead bin and definitely not in checked luggage.
I haven't flown in the past few weeks, but was this limiting to one Li-Ion
battery, or one
power bank?
I can't imagine how an airline could possibly limit travelers to just one
battery--they might as well just tell business travelers or any family with kids to stay home. Traveling with a phone, laptop, and tablet is practically standard, and that right there is three batteries. Last time I flew I had a phone, watch, AVP, Switch, electric toothbrush, electric razor, iPad, laptop and a small power bank, so was carrying seven Li-Ion batteries in a backpack that fit under the seat in front of me and two on my person.
Even a business traveler flying nearly naked (device-wise) with nothing but a personal phone and work phone is carrying two batteries.
Based on logic, I would assume that the AVP does not count as a power bank, but part of the device. If there was any worry about it being mistaken for a power bank on an airline that allowed only one power bank (and I also had an actual power bank), I would leave the battery brick connected to the headset while in the case, so it was clear if examined that it was part of the same device and not a funny-looking power bank.
I am rather curious how the no-overhead-bin rule is going to be enforced with bulkhead seats, where anything bigger than a phone
must be put in the overhead bin for takeoff and landing. Are they going to prohibit anyone flying with a laptop from sitting in a bulkhead seat because they can't stow their laptop for takeoff?
