Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[Q]: I've heard conflicting news stories and hearsay regarding the topic: Can I take a laptop (and also a digital SLR camera with a lithium rechargeable battery) as carry-on luggage on a flight from mainland Europe to the US? Is this policy expected to change in the next few weeks?

[A]: Are laptops currently allowed in carry-on luggage from Europe to the US?

[Q]: What I have:

1 Brazilian passport with the 90 no visa required days currently
maxed out
1 European passport

Why? I work online for myself so I can do it from anywhere and my girlfriend is currently living in Russia.

I've been in Russia for about 90 days with a Brazilian passport and now I want to go back before waiting 90 days.

What is the easiest passport to acquire a tourist visa with, Brazilian or European?

And if I decide to use the European should I say 'no' when they ask if I ever was in Russia?

[A]: Going back to Russia with another passport (maybe)

[Q]: I am looking for a place to leave 2 pieces of luggage for 3 days in La Paz, Bolivia - preferrably at La Paz El Alto airport (LPB)

Does anybody know if such a service is available there?

If one simply searches the internet, then the answer is yes - it is supposed to be somewhere in the main hall.

However, I was at the airport today, on arrival from Cuzco, Peru. I was specifically looking for this counter/service and was not able to find it. There was a single currency exchange counter, a souvenir shop and a hallway to connecting flights and that was it.

It seems to be a really small airport/terminal and also there is some construction going on - which might be the reason why I could not find it.

The webpage for the airport has been down for weeks and is of no use.

To give an overview of what I saw at the airport - first there were the usual passport check booths, right after the booths there was a single belt, from which we picked up our luggage. Then there was the customs check and finally we were in a relatively smallish hall with exit (to taxis) to the left and the currency exchange to the right of us. Maybe the international arrivals are just separated from everything else?

Does anyone know now for sure that this service really does exist as of December 2014? Maybe I did not look for it long and hard enough - if that is the case - where exactly would it be located?

[A]:
Luggage storage at El Alto La Paz airport
