There's always myUAdiscount too, assuming other airlines have similar to UA. I make less than most of you for sure and even with child support and having to fly to Fresno, Minneapolis, and Cebu often (Jeddah before that), I'm almost flipping Star Alliance Gold lol. I mean SFO-FAT for example is usually $350-600 one way to keep those seats open for juicy connecting fares from EU, Asia, and other places. With myUAdiscount, its $128-160 usually. If a few days out its already over 75% full, I just buy a ticket. $175 usually MSP-SFO, so since I fly in then work a few hours later, I buy a ticket for protection in case it cancels or I need a reroute or OAL rebook. •, SFO-MNL is like $358 in economy and I did Polaris MNL-SFO like $1700 which is a STEAL when you won't get it standby.
At age 36, I'm 100% "shut up and take my money" over the nonrev game if its reasonable. Dunno why pilots are so cheap, I mean you got there, you're getting paper, buy your commute tickets home and chill out. I get upgraded over 50% of the time I buy a ticket now.
