Hi ! I'm back with another question about baggage.

As a reminder, here are our flights :

1) LHR - MCO (09/19/2025) : Delta 5971 (operated by Virgin - VS91) - Premium (G) - A330-900Neo
2) MCO - LGA (10/03/2025) : Delta 2239 - Delta Comfort (W) - A321
3) JFK - LHR (10/07/2025) : Delta 5992 (operated by Virgin - VS46) - Premium (G) - A350-1000

And here's what I received by email from Delta :



We can see from this table that checked baggage is free, but the MCO-LGA segment doesn't appear (however, there is MCO-LHR) ! Also note that it mentions October 3rd, not October 7th.
So, I'm wondering if I'll have to pay for checked baggage (on Delta's website, it clearly states that it's chargeable on US domestic flights).
Do you have any ideas ?
