Standby to extend award stopover?
Hi all -- so sorry of this question has been asked, but I haven't seen this permutation before..I'm looking to book a SFO-LAX-LHR-(onwards) award ticket at some point in the near future, but I adore spending a day in Los Angeles with friends before continuing onwards.
Unfortunately, 24 hours for a stopover isn't enough for me in this city, and that's all that allowed by most frequent flyer programmes. Would it be OK if I were to tactically book an 11PM SFO-LAX departure, and then an LAX-LHR flight for the following evening, and then stand by for a 6AM SFO-LAX flight so as to extend my stay to >24 hours in LA? Does UA allowed standbys for 1P members on award tickets issued by partner airlines? Are SFO-LAX loads light enough to make this a reasonably fool-proof plan?
Thanks so much!
Edit: If UA adopts CO's +/- 24 hour confirmed standby policy, would this be a good situation where I might be able to use it to my advantage?
