Having been prepared for paying for everything on board other than water, coffee and tea the service was OK. Food and drink is expensive but the food was OK if limited in scope. Plane was clean and obviously well serviced. After complaining about having to walk in wind and rain to a get a bus to the airport the same thing happened at Portland. I’m sure you could get a terminal gate flight, complimentary food and drink for not much more money without traipsing through rain and slush in Reykjavik. Not bad but not great.

If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

Iceland air transfer was bad. They lost my luggage and I just received it 11/1

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

Service was excellent. Food and drinks were very good except for a greasy lump of a donut at the end of the flight that left us both feeling internally disgusted.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

It was good. The air plane is clean and staff were friendly.

Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service

Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.

Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

No WiFi working on either flight. No leg room at all, the seat in front of me left dents in my knees. If I put the tray down, it was so low it was propped up by my knees. (I’m only 182.9 cm) I’m usually cool on planes, but the planes were both hot during taxi and take-off.

The seat pads are past there sell by date now and are uncomfotable. Also, with screens in the back of the seat, the seats shouldnt be able to recline as this puts rhe screen in your face.

As I have said it sucked, the ticket counter to have to find and pay for another airline to get home. Now I understand this happened over the weekend but they should have someone there to talk to us instead of throwing the regular crew under the bus.

Poor all around experience. Sat at gate in Grand Rapids to Chicago for 2.5 hours. No food or water offered and no allowances to use restroom. Missed connecting flight to London and not offered any compensation including food or lodging. Not happy with AA, claims delay was weather related but no weather issues seen on radar. Take ownership for real reason behind delay which was actually the IT outage. Very disappointing and will not be recommending AA for domestic or international flights if this is the way that customers are treated.

Flight cancelled, lost luggage, crappy meal voucher. Nothing was good. Still dont have my luggage.

we had to walk up stairs to get into the plane--no jetways. Perhaps that's a problem not with the airline but with facilities at Heathrow, Glasgow, and Edinburgh. But it was inconvenient.

Not so good with their baggage handling as they damaged one of my check in luggage

On time. Clean. Efficient. Just what is required for the short hop.
