How to upgrade to Delta Comfort+ from Basic Economy?

Sorry bro, never going to happen. Basic Economy tickets are restricted from complimentary upgrades.

How to upgrade to Delta Comfort+ from Main Cabin?

Upgrades to Delta Comfort+ from Main Cabin are complimentary based on Medallion status, then ticketed fare class.

How to upgrade to Delta First Class from Comfort+?

Upgrades to Delta First Class from Comfort+ are complimentary based on Medallion status, then ticketed fare class. In reality, most daytime flights (especially on peak days) usually have 1-2 seats available for an upgrade which Diamond Medallion battle over. To maximize your upgrade changes, take the first or last flights of the day or fly on non-peak days.

NOTE: A ticketed Comfort+ W fare class makes upgrade rankings hard to understand because complimentary upgrades are based on the fare basis code. In essence, if two Medallion members at the same status (one in Main Cabin, one in Comfort+) competing for one First Class seat doesn’t mean the Comfort+ will be upgraded first. If your W fare basis code is lower than the Main Cabin passenger’s fare basis code, they will receive the complimentary upgrade.

How to upgrade to Delta Premium Economy from Comfort+?

Upgrades to Delta Premium Economy cabin are only available via SWU/Global upgrade certificates.

How to upgrade to Delta One from Comfort+?

Upgrades to the Delta One cabin are only available via SWU/Global upgrade certificates.
