We have often found that EUA does not run exactly.

Sometimes it runs the day before. Sometimes one or two days after. Depends on a whole lot of variables I don't know about, I would guess.

As a pair of platinums, we have never ended up with both of us not upgraded.... and I take the hit the few times we go 1 for 2. (Then GG usually sends me back a drink!). And the couple of times I've ridden in the back have been last-minute or reroute. We have never missed DCA in three round-trips, all through Detroit.

As a gold, you will find that your mileage may vary. Go for those extra miles to have platinum insurance!
