Possibility of meeting friend in airport?

I will be flying through the Frankfurt airport and I have a friend from Germany. I know that you can get a transit visa to leave the airport, but I don't necessarily have to leave the airport. I just want to see if there's a way that I can leave the international side of the airport to meet her, possibly through a transit visa? My layover is only 4 hours long but I wouldn't need to meet with her for more than 2. If this sounds like a possibility, what would I have to do to reenter the airport?

Are all airlines using the bait and switch business model?

Delta NY to Denver. $262 round trip on the red eye. Want to take any bag, carry on, checked, doesn't matter… It is now $700+ round trip.
I go empty handed. I buy what I need, then throw it out when I leave. It isn't worth $100. I bring nothing. A sandwich bag with my prescriptions in my pocket. A comb and toothbrush in another. If it doesn't fit in my pockets, it doesn't travel. Not environmentally good, but this is what air travel has come to. If you told me this 5 years ago, I would have laughed at you.

Is getting around Narita Airport easy?

So I'm going to Japan for 10 days in September and I will be landing at Narita Airport. I'm a little nervous I may not find my gate or check in counter. Is it easy to find my gate and is there people there that will direct me to my proper gate at the airport when I go back home to New York since it's a big airport and do most people there speak English?

Airline fare question. I'm booking my first flight. I will be traveling alone. What're the differences between main cabin and basic Econ?

My saved bookings go through either AA ord Delta. I'm trying to figure out the differences between the main cabin and basic Econ. I'm willing to pay the extra 60-70 bucks if it's truely worth it. I'm not worried about earning miles or cancellations and changes. I know the selling point is seat selection, but how does that work? Do you pay for the higher fare like a premium but still have to pay for the selected seat? Is there extra leg room? Are amenities like Wi-Fi, movies, drinks affected?
