I booked flights for my wife and I from CLE to BCN (through ATL) on Delta in July. I got a good deal on the flights - $2170/flight in F.

This issue is that I booked the flights on the Delta website, where I could not enter our Onepass #'s during the booking process. I figured that I would do that later, maybe even at checkin. CO says on its website that we can get 150% EQMs for any Delta F flights.

The reason for this post is that I just heard that to get CO EQMs for Delta flights, I had to enter our Onepass numbers at the time of booking. Does anyone know if that is true? Did I miss the boat for CO EQMs? I will call the Delta support number provided on the CO website and fight the fight, but I would like some advice/ammunition before doing so.

Also, the ATL-BCN and BCN-ATL legs are I class tickets. Does anyone know if these qualify for the 50% bonus?

Thanks in advance for your help.
