Short answer, yes, and that happened in only one bid.
Upgrade will likely be faster at Delta then Southwest due to retirements and lower category airplanes. A more fair comparison would be when can you hold the left seat of the A320 or B737 at Delta over the last couple bids. I'm guessing that's currently in the range of 4-6 years at Delta, not less than a year.
