You will earn 175 Elite Points for your JFK*MAD segment.
You would need another 95 Elite Points. If you want to fly some USA domestic flights, you need to look at this table to figure how many Elite Points you will earn by flight distance/booking class --> See Avios Table
https://www.iberia.com/us/iberiaplus...ican_airlines/ [even though it says Avios table, it also shows the Elite Points Table]
Anyway, don't make many plans... your flight might be cancelled regardless. Also, if you upgrade, you will only receive Avios and TP based on original booking class (this is not BA, where they honor Avios and TP based on the upgraded class).
