Important: Is it really an Iberia flight from London (LHR) to New York (JFK)?
Often, an “Iberia” London–JFK ticket is a codeshare—meaning the flight can be operated by another airline (commonly American Airlines or British Airways) while still marketed with an Iberia flight number.
Examples from Heathrow’s flight info pages:
-
Iberia flight number shown, operated by American Airlines under codeshare.
This matters because seat selection, baggage rules, and onboard service may follow the operating carrier rules—not Iberia’s.
