Turkish as a great choice (flew direct - great service and food)

JoeFlew with IberiaORD-LHRApr 2025

Get there early. Nice airport options while you wait.

Verified travelerFlew with Aer LingusORD-DUBApr 2025

Security at OHare airport is a bid shambolic. Not enough space for the amount of people trying to process.

TFlew with Scandinavian AirlinesORD-CPHJan 2025

Don’t forget you can pinch and slide the headrest up and down for maximum sleeping comfort.

DinaFlew with United AirlinesORD-LHRJan 2025

Anticipate delays, prepare for long walks through Heathrow to baggage claim or for connections.

RuthFlew with United AirlinesORD-AMSDec 2024

Hopefully you’ll be in a good tailwind and arrive early.

LOT provided good service for the reasonable price. Fly it!

Verified travelerFlew with SWISSORD-ZRHSep 2024

Bring a neck pillow and a heavy sweater bc it does get cold. I used the blanket for my legs. Also: get a seat in the aisle.

Verified travelerFlew with LufthansaORD-FRASep 2024

I personally like Lufthansa, draw back are the distances to walk at the Frankfurt airport.

Verified travelerFlew with Turkish AirlinesORD-ISTNov 2024

Turkish doesn't maintain time, flights are mostly delayed, their crisis / situation management is terrible when a flight gets cancelled, communication / customer service is the worst in the industry.

RuthFlew with United AirlinesORD-AMSOct 2024

Facial recognition seemed to slow boarding down, not speed it up. Why don’t airlines board from the back to the front? That would certainly speed things up!

Verified travelerFlew with United AirlinesORD-FRASep 2024

Be prepared to wait in long line for boarder control. Allow enough time for your layover

FrancescaFlew with IberiaORD-FCOJun 2024

Expect small seats, narrow spaces for luggage and in aisles, but very nice flight attendants

MikeFlew with British AirwaysORD-FCOJun 2024

Make sure you check the plane type and economy seating space.

Pick an airline with more flights to Reykjavik

Verified travelerFlew with United AirlinesORD-LHRJul 2024

Even though you may have a delay or two the important part is that you arrive safely from one point to the next. I wish I could get some credit back since I paid for a nonstop flight and ended up having a connecting flight.

Verified travelerFlew with British AirwaysORD-FCOJun 2024

Get on an early flight and do not fly American

ChristopherFlew with American AirlinesORD-HELApr 2024

Do it! The flights are cheap and comfy. The best combo. I didn’t have an issue, but there was a person who was vegetarian and they if you don’t request a meal ahead of time, they don’t have multiple options. They only had a meat option for dinner (which was amazing).

Verified travelerFlew with Austrian AirlinesORD-VIEMay 2024

Austrian airlines overall created a positive experience. Vienna airport is well organised and passenger -friendly. Chicago airport is quite busy.
