The terminal for this flight, 4S, was INSANE. So many Iberia desks, and it wasn't clear which ones were for which destinations. When I checked in, I asked if I could check my bags to LAX, my final destination, but was told no because my next flight was with another company--I would have to gather my luggage and then deposit it again in London. Annoying, but okay. Then I went through Security, where I was asked to open my luggage, berated for having water (which I offered to throw out), and just generally hazed. After Security, I went up and down countless escalators and then boarded a tram, which literally went miles. Following the tram, there was ANOTHER escalator and ANOTHER line, this time for passport control. At 10:25, I told officials there that I was on a 10:40 flight, but nobody seemed concerned. So after clearing passport control, I RAN all the way to the gate, where my boarding pass was scanned, and then ran along the gangplank. At this point, I expected to board a plane, but what I encountered was a STAIRWELL, with steep stairs leading downward. Astoundingly, I didn't see any elevators or escalators. I lugged a suitcase, large bag and jacket down three to four flights of stairs, expecting to board an aircraft at the end, only to encounter a bus outside. After all the hoops we passengers had just jumped through, I was floored by this. And because the bus driver was waiting for other confirmed passengers, the rest of us were standing on the bus for at least ten to 15 minutes. Once the bus FINALLY set off and then dropped us at the plane, which was sitting way out on the tarmac, we all had to cart our luggage and bags up ANOTHER steep set of stairs onto the plane. In 100-degree heat. Parched from the physical marathon I had just endured, I was thinking that once we were in the air, the flight attendants would pass out water. Instead, they went down the aisle asking if anyone wanted to order and pay for a drink, but they never asked me or many others if we wanted anything—they picked and chose passengers to ask. I raised my arm to try to get their attention, as I was desperate for some water, but they were avoiding almost all eye contact with the passengers. So I arrived in London completely dehydrated. Then I went to baggage claim. After waiting for about 20 to 30 minutes for my bags and not seeing anything that resembled mine, I started looking at my phone. That's when I saw an email from Iberia saying that there had been an incident with my luggage, and that my luggage had not made the flight, even though I had done the Madrid baggage drop in good time. Also, if I hadn’t checked my email, I don’t know how I would have found out that my luggage was missing, because there weren’t any reps at baggage claim. When I spoke to the Iberia representative about it, she said that the luggage would be arriving on another Iberia flight at 3:00 p.m. that day, but I was scheduled on a Virgin Atlantic flight departing London at 3:45, so picking up my luggage at 3:00 p.m. and rechecking it wouldn't be an option. After everything that had already happened that day, this was really disappointing. I didn't see my luggage again for two days. Honestly, it was just such a bad overall experience that I can't imagine flying Iberia again. And it was surprising, because earlier in the trip, I had been on the Renfe high-speed train from Barcelona to Madrid, which was a really good experience, so I had high expectations for Iberia. This could have been an aberration, but since it has been my only experience with Iberia, it is my only reference point.

Delayed our luggage going to Croatia and delayed our luggage coming back from Croatia. Not very good service.

Terrible - worst airline on the plant - flight delayed; misses connection - no effort to accommodate an alternative schedule. Had to fight for a food voucher. Put us up in a one star hotel that was an hour plus bus ride from the airport. They should be ashamed of themselves.

Was downgraded from Premium Economy to Economy and no indication of any compensation.

We were never contacted that our flight from Glasgow to London was delayed. Got to airport six hours early to find that we were going to miss our connecting flight to BWI. Our flight is scheduled for two days later and they only gave us a voucher for one night hotel. E we’re delayed on the front end too and had to fly to Edinburgh instead of Glasgow arriving six hours and taking a $200 cab!

It took an hour and a half for luggage to be dlivered in London

We were seated in the rear of the plane. Buses arrived to take us to the terminal but there weren’t enough so we waited an hour to leave the plane.

The 7 hour delay in Johannesburg was extremely tiresome, with poor communication at check-in and a sad R120 voucher as compensation. All in all sitting for 10 hours on an airport was pretty bad. At arrival the baggage arrival took 2 hours. All in all, a very, very long trip.

Chicago to London flight was delayed an hour . Boarding process was slow . I missed my connection to New Delhi and My connection from New Delhi to Ranchi. Now come the really outrageous part! There was a flight from London to Bangalore that would have allowed me to reach Ranchi on time. I was about to but ticket from Bangalore to Ranchi when BA agent came back after talking to someone in back office and informed me that she cannot rebook me to London Bangalore flight as Bangalore was TOO FAR fro. Delhi. I waited 8 hr in London airport. I was flying business. Hope this review helps the airline. I was not asking for any money back for my missed flight. Anand Mohan

Bad. Bags are missing, there was no wheel chair assistance provided
