Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

I wish they could put the pre-tsa check on the tickets or global entry.

Couldn’t keep my luggage and had no choice. Ground staff didn’t even bother to explain why.

We upgraded to Business class paying approx. $1,300. Despite the upgrade, we were still required to pay an additional €70 for a checked bag. Furthermore, we were informed that another €70 would have been charged for our carry-on bag, as it was 3kg over the limit. To avoid this, we had to move clothing from the carry-on into the checked bag, which was both inconvenient and frustrating. Given the significant amount paid for the Business Class upgrade, we found this treatment to be quite appalling and disappointing. We expected a higher level of service and consideration for our luggage, and this experience did not meet those expectations.

Great flight, short and good attention. Didn't took any food so can't say thing about it

Excellent with no delays and according to the time schedule.

Its a bus taking you on and off the plane so if you have big luggage … more muscles needed

Flight LIN MAD. Checkin was fine (but I must admit that being a Platinum member I skip the lines). Security was fine (they have the new machines where you need not take laptops or liquids out). Longe was OK (BA). Boarding was a mess, the boarding gate personnel were rude and some should simply not be in a customer facing position. Flight in itself was fine, usual Iberia European coach. We were on time and actually time to deliver luggage was better than normal for Barajas

Great food, excellent service. Did not manage to make wifi work but in a flight of less than an hour it was not a big deal
