As of October 2019, the project had used about 76 percent of its available schedule reserve and no longer plans to launch in November 2020 (see figure). The project is now managing to a March 2021 launch date but estimates only a 12 percent likelihood that this date will be achieved. NASA plans to reassess the launch date in the spring of 2020.

They better not launch it in March, or any other time. Tens of thousands of jobs will be lost if they do. This is a political shelter thing ya'll know. And if they did launch it it'll be outdated. So why bother? Has any other program been delayed this long ever?

Keep it as the training program it is.

The launch of the NASA/ESA/CSA James Webb Space Telescope (Webb) on an Ariane 5 rocket from Europe’s Spaceport in French Guiana is now planned for 31 October 2021.

NASA has announced the decision, based on a recently completed schedule risk assessment of the remaining integration and test activities before launch, accounting for impacts from the COVID-19 pandemic and technical challenges. Previously, Webb was targeted to launch in March 2021.

I don't think JWST will ever launch this year, because it has gone to several decades of testing, because JWST will orbit around the Earth-Sun L2 point, the orbit of inaccessibility by humans.

Edit: The previous revision said that it was L1 point.

Better not rush it. Hubble had to be repaired short after launch. Won't be an option with JWST, it has to work. Given the money and time invested in that project I can understand NASA is a bit cautious.

Also Hubble was a revolution in astronomy. It now has to be replaced, and failure is not an option. It would be a severe setback.

I was in the firm belief that the telescope was flying on Ariane 6

Yes Ariane 6 faced many delays. One of the reasons is probably that Ariane 5 now just works really well...

And JWST is the kind of unique payload that require excellent reliability, would be too risky to fly it on a "young" vehicle anyways. Right now I think Ariane 5 is really well-suited for the task.
