Checking a bag at KEF was time consuming due to long lines despite having a business class ticket

Checking a bag at KEF was time consuming due to long lines despite having a business class ticket

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

The plane was flaming hot! Could not breathe. Everyone coughing from heat. Awful.

Food and staff were excellent. Seats on Saga (business class) are comparable to domestic first class of US Airlines, regarding space and recline. Entertainment options had little international component.

Flight delayed Delay to the gate upon arrival Baggage took more than an hour so we missed our connecting!!! Terrible experience!

There is no food without paying $. Only soft drinks are included in your fare.

Some drinks and basic snack will be good. Water should be served at least once an hour. Blankets for folks who might be cold.

Pros: "Flight was relatively empty. Professional crew, comfortable seats"
Cons: "I think they skipped me with food service. Checking up on passengers who may have been sleeping would be nice. Headphones need to be purchased. Limited entertainment options."
Cons: "Communication about international COVID requirements before the day of departure."
Pros: "Easy flight, and boarded in the front and back of the plane. Made it easier and faster to get on."
Cons: "They aren’t too clear in baggage charges. I got standard fare, but still had to pay for my checked bag for both ways."

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona

They allowed some guy to move seats after 3hours of him being next to someone very sick, There were several empty seats, but they moved him to mine. I find that incredibly inconsiderate and should not have been done.

Excellent. Very nice and comfortable business class. Only negative is that it was difficult to hear the pilot’s announcement.

Food not so good. Need more veggies and whole grain especially the late food. Couldn’t figure out how to use the entertainment system.

Check in was horrendous! Economy took 2 hours before seeing an agent. Business class was 0.5 - 1 hour.

The first class flight itself was first class, however getting to the airport and getting through the airport was agony. The BA flight sat on the taxiway for ages and caused us to miss our connecting flight which meant half a day lost. Our return flight on BA was cancelled so a dawn flight was made and we lost another half day. Goodby BA

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

They cancelled our ticket, gave us no warning, they reissued it 4 days prior to trip and it was cancelled again when we got to the airport- very stressful, the flight was overbooked so they drove us across Milan to malpensa
