Airline reviews

Boarded in group three at Barcelona, which meant going from a gate outside onto a bus to ride across the airport to a plane waiting on the tarmac. When we arrived at the plane, crew behavior told us something was wrong. Bus driver would not let us off for almost twenty minutes, despite being crammed shoulder to shoulder. Eventually, we got onto the plane, but were then told that someone “forgot” to refuel the plane and the truck to do so had not arrived. We departed late enough that we missed our connecting train in NYC, which was the last train of the evening, so we had to stay awake all night in the passenger waiting area of Amtrak’s Penn Station, which was almost impossible to get to because the station was now closing, as it was after midnight. We had to haul four suitcases a few blocks on city streets in the rain to get to the one remaining open entrance to Penn Station. We ended up being up for 36 hours straight because someone couldn’t do their job. Never, ever again would I fly this airline.

All four segments of my trip on Iberia were late for various reasons. No apparent effort to stay on schedule. Never flying Iberia again.

The flight from Madrid to Boston was awful. Without prior warning, I was seated in the row in front of an exit row where my seat did not recline. The person in front of me reclined, reducing my already tiny space further. This was the WORST flight I've ever had.

Without any prior warning, I was seated in a row just in front of an exit row (27F), and I had no idea that my seat would not recline. However, the person in front of me did recline her seat, reducing my space. And because I could't recline to regain some space, it was my WORST flight ever.

Overall it was okay. Just the lost baggage and how they are handling it

Puddle-hopper. Quick-ish flight. Don’t expect to have much/any in-flight entertainment (movies/TV, etc).

Worst flight I ever experienced, what was supposed to a 7 hour flight ended being 13 hours on a plane with no ac and the worst cabin I have ever seen. Never again.

Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

I’m an Iberia fan but this time They dropped the ball. I went from ALC to MAD to LHR. Boarding in ALC was by group… to get you in a bus. Then we sat for almost an hour when most people had connections. When we landed in Madrid we did so and they put us in another bus almost like if they wanted to make people lose their connection. We made ours by the skin of our teeth but our luggage did not. And on top of this we had to listen to the pilot bragging about Iberia being punctual. To be true we made it on time to LHR but we are Still waiting for our luggage

okay, will recommend from PR to Madrid, faster turn around
