I'm about to be travelling with my 2yr old daughter alone. We will be having a seat each. 1) how many checked bags&carry ons are we allowed? 2) can i bag check a car seat? Is there a charge? Will this be in addition to bag check allowance? 3) can i also gate check a stroller? Is there a charge? 4) is family boarding always available? 5) is there family security lines? Or do we wait in a regular line?
