While I wait for my UR-SQ to post TK business opened up for my dates, which is better than UA F to LH fake J per opinions above. Of course this will leave me with leftover SQ at this point, unfortunately, but still seems like a better plan (and hopefully I'll sell the SQ eventually) I assume that's also better than my other idea of waitlisting SQ J for the JFK-FRA leg. Unfortunately suites aren't available even for waitlist for the date I need, and because of childcare arrangements my dates are not flexible.
So would the experts here agree that TK J > SQ J + LH fake J > UA F + LH fake J?
And how would that calculation change if I could potentially get SQ suites, if they open up (at least for waitlist) before I book?
