Wow! What a romantic story, and I hope it has a romantic outcome! It certainly did make my day! : )
If you know her final destination was Ontario, California, you can choose to put a personal ad on Craigslist in her city, or a city closest to hers, and/or place a personal ad in the local newspaper of Ontario. In the ad, mention her first name, you met on a plane (flight number) the jewelry designer information, and also, since you know she designs jewelry, call a few jewelry stores or outlets in Ontario and ask if they are familiar with her/have done business with her. Explain your story, and if you're lucky enough to find someone that knows her, or knows someone that knows her (sometimes, this is how it goes, when you get 'leads' which lead to other leads,) tell them if they do know her, you're not asking them to give you any personal information about HER, but just to get a message to her that you called, explained who you are, where you met, etc., give YOUR contact info (telephone, or corrected email, etc.) and ask that she get in touch with you.
If she actually has a business selling her jewelry (jewelry designs), you might check sites online, through google or other similar search engines, with keywords, 'her first name', jewelry, jewelry designers/designs, and her city, and see how that goes. Also, try to remember what else you discussed on the plane, and if she mentioned any favorite stores or restaurants she frequents, and if you can, try to go there.
Also, even though the airline won't release the information on their passenger list, etc., if you call and explain your situation and give her first name only, then ask, as I mentioned above, for THEM to contact her and relay YOUR contact information to her, maybe if you get a cooperative/romantic customer service rep, they might do you this favor. Again, you're not asking for any personal info of HERS or how to find her, just to get YOUR information to her, since you goofed with the .com, .net. Sometimes, you get a really understanding person who will actually help you.
You can also try to count on the fact that perhaps, if she's computer savvy, she will try your email, see that it's not right (her email will be bounced back to her, if there's no other person/company with the same email address with .com) and she WILL try the .net or .org, just to see if it will go through.
I hope you're able to find her, and this has a very happy ending! Please keep me posted on your progress and if you find her. Thanks!
