I've found in First Class, the flight attendants (at least on US Airways) tend to be a little more lenient in this regard. Usually the lavatory for First Class is not very far from the seats. A lady on a flight I was on last week went to the lavatory while we were still climbing and was not challenged. She apparently was in dire straits as she was in there for at least ten minutes.
@DavidRicherby ok, thanks for the explanation. I thought they took the thick laptops out of bags so they could X-ray them easier if they were separate. I hadn't thought about them "hiding" something underneath.
@DavidRicherby That makes sense too. However I know in the past, I have had my laptop wiped with a special cloth and then the cloth put into a scanner to check for explosive residue, so I think there at least used to be a risk for that. Also I thought the reason they had you boot up your laptop (which they did for a while, a few years ago) was to make sure the insides were not compromised.
I'm currently working for a startup company in Arizona which I believe has similar dress standards as California -- even the 50-something CEO wears jeans sometimes when he is not going to be meeting someone. There is one fellow that wears either a vest or a sweater every day of the year, and boy does he stand out - he gets kidded about it some, but keeps wearing them. It really does look much more formal than the rest of us in our polos and regular (button) shirts.
US Airways has the same policy also -- I noticed it on a sign at the airport when checking in for a flight last week. First two bags free if going to Brazil, and much less charged for additional bags. Same policy for transpacific flights (except high charger for 3rd and 4th bags). For transatlantic and rest of North/South America/Caribbean they charge for 1st bag on up.
@user27478, You are correct, I missed the single-ticket part. BY definition, if one airline doesn't interline with another, you can't buy connecting tickets.
In the US, Southwest Airlines does not provide seating assignments (except for an additional fee), even after you get to the airport; all aircraft are boarded by zones (A, B, C). Once on-board, one has to scramble to find the seat you want.
