Traveling on DL0253 JFK-BOG on 29-March. This flight has Main Cabin, Comfort +, and First Class.

Recently status matched to Silver. Should I be eligible to request a First Class upgrade even though this is an international flight? According to the benefits chart, I think yes. I was able to request for the domestic section on same PNR, but for this segment only Comfort + shows as available to request upgrade.

Thanks for the help, as I switched from AA and still learning the new rules. I know you can’t request for Delta One, but that’s not offered on this flight.
