I'm going to be booking a redeye for May 25th (Wed) from ONT or LAX to ATL.

Since I'm only SM I know that the chance of an upgrade is low BUT just curious whether people thought the the load in C was generally better coming out of ONT than LAX, which is my guess. Since both are going to ATL I assume there will be a lot of Medallions on either.

I'm likely to be doing this flight a lot more and hopefully when my status is higher I'll have more luck with upgrades, so I'm interested in what kinds of odds people see.

Thanks.
