When flying abroad is it cool to buy a bottle of wine in the Duty Free shop and open it on the plane in lieu of paying $15 for several tiny little screw cap bottles? If so, how do I get it opened? I have had several (many) corkscrews confiscated.... do they take Osso cork pullers as well? You know the two prongie ones that you have to wiggle in.
For international flights, a couple are a little looser in their security- namely, New Zealand and Japan but, that's also only for domestic flights within their countries.
You can bring on a corkscrew now, just make sure it doesn't have the foil cutter blade on it because those are still outlawed by the TSA. I would think that if they're afraid of a small foil cutter then you wouldn't be able to bring on your Osso :(
The main law is against you pouring your own wine in-flight which is interesting because I, myself, have had wine (luckily much better than Sutter Home and free on Horizon on my way to Santa Rosa) and poured it myself. So, my main tip for you is to buy a flight or screw cap bottles in Vino Volo shops that are post security hassle, grab a couple of Starbucks cups to hide the wine from spying flight attendant's eyes and keep it on the down low when you pour!
