Momof 2d,
I don't think the OP was posting to ask us for a solution to the problem, I think she/he was just venting. I know I often have frustrating conversations with my husband about little problems at work and he right away jumps in with a solution when all I wanted was a, "Wow, that's tough honey. What are you going to do about it?" I think bulletin boards often serve as vent boards.
Also, venting here is probably much better then getting into a family squabble as you correctly pointed out.
You DO NOT have to register your child as an unaccompanied minor, that is not a given. All three of my kids have flown by themselves without us registering them before they turned 16. I know three foreign exchange students (who did not speak English very well) that missed a connection last summer at O'Hare and were told just to wait for the next flight - in six hours. So they did, not realizing that there may have been other choices.
This is interesting - I just googled, "airlines, unaccompanied minors" and a quick look shows that each airlines interperts this differently. Here's the scoop from United,
"12-17 years (Optional)
Unaccompanied minor service is available, but not required, for this age group. We strongly recommend that teenagers who are not using our unaccompanied minor service be confirmed on flights early in the day. Unanticipated delays or cancellations and unexpected weather such as fog, snow, thunderstorms or air traffic congestion may disrupt flight schedules and result in misconnections.
If delays result in travel the following day, United may not be able to offer overnight accommodations since many hotels will not accept minors aged 17 or younger.If unaccompanied minor service is requested, standard fees will apply.
If a child aged 12-17 years is traveling as an unaccompanied minor, he or she will be accepted under the conditions specified for unaccompanied minors aged 8-11 years."
Southwest only calls them unaccompanied if they are under 12!
Continental says, "Continental will allow unaccompanied minor travel only on Continental Airlines, Continental Micronesia, Continental Express and Continental Connection flights.
Unaccompanied minors under 5 years of age are not accepted.
Unaccompanied minors ages 5-7 may only travel on nonstop flights.
Unaccompanied minors ages 8-14 may travel on any flight (nonstop or connecting) operated by Continental, Continental Micronesia, Continental Express, or Continental Connection. However, travel will not be allowed on the last connecting flight of the day – unless the connecting flight is the only published service to that destination. Unaccompanied Minors are not accepted on flights which require an overnight stay in order to make a connection.
Special supervision for children ages 15-17 who are traveling alone will no longer be offered.
Children under the age of 15 traveling alone may not travel on any flights operated by Continental that connect to/from other carriers, including SkyTeam and other partners."
There's more but this post is probably long enough. My twenty one year old son says that I should be accompanied more then his younger brother!
