hello! i was recently added as a flight companion under my friend. she told me that i could take any flight free as long as i paid taxes and it was standby. how does this work? i have never stepped foot in an airport- let alone flown, especially with a baby. i know my daughter can be a lap child and that is it. help please! any tips, tricks, or info would be gratefully appreciated
