I was originally going to book a first class award flight on the returning home from Europe from MXP - JFK next summer to experience the A380 first class, the showers and bar, but there’s no availability.

Instead, I booked a first class award flight headed to Europe from EWR - ATH on the old 777 at the end of May that popped up. There aren’t many online reviews or videos on this route, so just wondering if anyone has flown this flight before and had a really good experience on the old 777? Or would it be better to hold out and see if availability opens up for the MXP - JFK daytime flight in the A380? Thank you!
