Just to clarify on the above point (from the experience noted above) - my partners Mother lands into Madrid from Montevideo tomorrow morning with Iberia at 6.15am in business class and is connecting (on a separate ticket) to Lisbon 11.25am in economy. Would she likely be able to access the lounge? It's after 6am (but only just) and most days arrives a good 30-40mins earlier then scheduled so what are the rules here for lounge access?
