Does anyone know what 9w charge for domestic excess baggage.

I will be arriving into del tomorrow (LX F) connecting to 9W Y to Hyd. My checked luggage is currently 37kgs... way over the 20kg limit for 9w y.

Also do 9W do on departure upgrade to J, depending on the excess baggage charges I might upgrade to J if the upgrade fee is near the excess baggage charge.

I am currently in transit in zrh, flight to del departs in 4 hrs. I hope someone can answer my questions by then.
