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

[EX Q]: My girlfriend is flying from to Missouri later this month to visit her family. Her sister, in Missouri, wants her to bring her game consoles so they can play games together. She will also be visiting for a month.

How can I safely pack these items with her? She'll be bring two consoles, a couple of games for each, a laptop, tablet, books and clothes. So far, my idea was to pack everything that can't be damaged into a checked bag, bring the consoles in the overhead bag, and her tablet/books in her carry-on. Is this a good strategy to prevent the most probably damage? What sort of accommodations should I make for going through security? I won't be going with her, so I can't go through security with her, or tell her how to get to her gate. The other option we've found is to have it shipped over there, but that involves paying to ship it over, and paying to ship it back.

[EX A]: Packing sensitive electronics for flight

[EX Q]: A few weeks ago, I booked a flight with Transavia going back from Prague to Paris on the Wednesday 10th June 2015.
Yesterday, I received an email saying "your reservation has been updated, click on the following link to see the new time for your flight" and on the linked web page, the flight appears to be on the 12th June.
I have not acknowledged the change yet.

Changing the "time" of the flight by 48 hours seems a bit extreme to me.

Is that legal at all? Is there any procedure to ask for compensations for the additional time off work I'll need to take or for the extra hotel nights ?

[EX A]: Flight rescheduled, what are my options?

[EX Q]: I have read that many hostels have kitchens or kitchenettes where guests can cook. This is something I plan to do. However, it's not too clear to me what's provided. Do I need to bring my own cookware?

[EX A]:
Do hostels provide cookware?
