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

Ex Input:
I live in Canada with a German passport and a student visa. From a recent climbing trip to the US I still have this green I94-W form in my passport. I didn't surrender it on leaving the US back to Canada, because I expected to come back for another climbing trip relatively soon.

That trip got postponed a few times, and now the situation is that the I94-W would expire while I'm on the trip. That is, it would still be valid on entry, but not on exit.

Can I apply for a new I94-W at the border crossing, or can these Visa waivers not be extended back-to-back?

Ex Output:
Extending an expiring I-94W, land based entry to US

When paying by card flight attendants usually ask to see your ID, to verify that the card in fact belongs to you. However it seems weird to me that pretty much no other merchants ever ask to see your ID, even when conducting purchases for thousands of euros (e.g. at IKEA).

So why do airlines insist on verifying your ID when paying by card? I understand that there's (usually) no Internet to verify the card balance on the plane (as suggested by TonyK), but how would one's ID help them out in case the card is empty?

Ex Input:
I am flying with EasyJet next week from Glasgow to Geneva, for my ski holiday.

I noticed the flight times are unusual in that my outbound journey is much longer than my return flight home.

Outbound
Dep 12 January 2013 10:40
Arr 12 January 2013 13:55
Flight 6835

(3 hours 15 min later)

Return
Dep 19 January 2013 14:35
Arr 19 January 2013 15:55
Flight 6836

(1 hour 20 min later)

Now I am not the best at maths but you can clearly see there is a major time difference in both flights.

Is there any reasoning behind this? I tried searching the Easyjet site but could find no justification for this.
