My family is taking a trip to Australia in a few months and I was curious to know from those of you who travel quite a bit internationally on other airlines your thoughts on how to travel when there is more than one person going. Through my airline I will only have the option of United to get my wife to Australia so it will be out of LAX most likely, but possibly SFO. Should I simply purchase an ID90 ticket for myself or try to jumpseat and save the $300. What are the advantages for both? Is jumpseating back from Australia an option or will I need to buy an ID90 ticket for the return flight from Sydney. Thanks in advance for any help with this.
