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.
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.
Verified travelerFlew with United AirlinesORD-KEFJun 2024
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.
Verified travelerFlew with British AirwaysORD-LHRMay 2024
Make sure you get a airline that allows one check-in luggage and respects its customers.
Verified travelerFlew with LufthansaORD-MUCMay 2024
Anytime you have a chance to fly Lufthansa, you should!
FreddieFlew with IcelandairORD-KEFMay 2024
If you’re in business class board first to avoid queuing
AaronFlew with American AirlinesORD-LHRDec 2023
Find a flight where you are allowed to choose your seats before the day of boarding for anything international.
MikeFlew with KLMORD-AMSJan 2024
Do not fly KLM if they put you on a small plane. We got downgraded to basic economy after paying for an upgrade.
