Flights from Southeast Europe to the United States: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Southeast Europe to the United States 
Paul T.Flew with American Airlines-Sep 2026
Wear multiple layers on the plane and do not underestimate how cold it can be Being sandwiches onto the flight as the food served is poor

Make sure you get to the airport three hours early in Athens the security lines are a nightmare. They are pulling other airlines out of the line ahead of you. They are pulling other passport types out of the lines ahead of you. You will stand there forever, no matter what clearances you have. Avoid Chicago airport at all cost. The place is falling down. They are elevators are out of order a few elevators that they have have lines so long that you will never get through before your flight takes off. People with carts of luggage are trying to get on the elevators with the handicap. It is a total zoo and if the temperature is 95°, the Air Conditioner can only cool to 89°. No you’re going to sweat to death.

Boston is one of the most difficult airports to navigate when returning from overseas. A long walk thru the overseas terminal E to customs, then after waiting in the line to clear customs, you have to retrieve your checked bag and take another long walk to the domestic checked bag location. Then you have another loooong walk to the domestic terminal (A or C) for your connecting flight. A bus is provided, but they are infrequent and often too crowded to board. All in all, you need about 90 minutes between flight (minimum!)

Do not sit in the aisle seats with no seat in front of you. We sat in a 3 seat row with a two seat row in front of us. The person that sits on the aisle is basically the cart stopper, since the food carts are basically using that person’s knee to guide and stop the food cart. Also passengers going to and from the bathrooms are constantly bumping into you and stepping on your feet.

Buy your meal and choose your seats when you book, because if you want to add them later, their website has issues.

Emirates has the best baggage and in flight options. I would recommend flying from Newark instead of NYC or Philadelphia for better prices and public transportation options back and forth

Make sure you come prepared, at least when it comes to food and drinks, unless you want to pay extra!

No bathrooms before customs. Takes about 45 min to an hour for luggage to get from plane to where I can pick it up to transfer it over. Area feels dirty

I have flown with LOT several times and regret it every time; however, they are the only airline that offers the direct flights I need. Boarding was awful. I was alone with 3 children, including an infant, and we were forced to stand in buses packed like sardines. Then, for such a large flight, there was not even a gangway. I was expected to carry a baby, a carseat, and luggage by myself up the dangerous steps into the plane while the crew RUSHED me. The crew was very curt, cold, and inattentive. No one offered any assistance or sympathy to me alone with kids. There was no ventilation or AC in the plane.

My ONLY complaint with LOT was the lack of WiFi and the food in business class… still, I use them because they have great connections to Chicago and they fly the 787 - which I think is a great wide body jet. Well… now LOT has WiFi (good satellite speeds) and AMAZING food. LOT now is giving Turkish Airlines a big big run for the money. And they consistently have less expensive business class. I am a very happy customer!

Issue with boarding, group of passengers on a religious trip coming back to NYC kept trying to change seats, even standing when the plane was pushing back. Crew/Pilot kept very good composure, some passengers got aggravated and started venting out loud but this group created a serious security risk. Crew/Pilot should've been more stringent and called in security or remove them from the flight.

Amazing crew, delicious food and drink selection. 12hr felt more like a 4hrs. Comfortable beds. Can’t wait for the new business class cabin

Flying business class saves you. Once you get out of the terminal and onto the plane, it’s fine. The traffic at the gate is a horror. No organization at all. The fact that Business class is promised early boarding is a myth.

The seat was paid for but given for some different person .

Krakow airport is very disorganized. nice seats. friendly crew. long legs had screens. short leg did not

Horrible communication, flight boarded then we sat on plane for almost 5 hours as the runway was barely covered in snow with no plows in sight and the as we tried to taxi there was a major equipment failure due to poor push off technique causing all passengers to be taken off the flight to ultimately have the flight cancelled. There was barely any communication to passengers as to what was happening or what to do next to get placed on another flight. Arriving to my final destination a whole day later having to take a connecting flight through Lisbon to ultimately end up in New York instead of a direct flight as none available for the next day. Never flying LOT airlines again!

Smooth flight, excellent crew and good food. Not enough space; sitting are too small.

Flight was delayed for a hour from Warsaw, not sure why. When we landed in Chicago, plane was still on the runway for about half a hour. Took a while to get off.

Hospitality and service of the staff were excellent. Food was good. The seat was not as comfortable as the other Airlines that I have experience with.

I was in the premier economy and enjoyed the room and the comfort. Although I will say that it would take a real expert to make the location of the place to plug in headsets and chargers more difficult. With all of the room available it makes no sense to bury those connections and to make it so difficult to use them. The couple in front of me needed to use the cell phone light in order to see where to plug in a charger. The seats are comfortable and the food was good.

No way to add a bag without getting in line at the counter, which took at least half an hour. No WiFi.

The preboarding and the gate organizing management was poor, unorganized and mismanaged. While standing in the business line I kept getting ignored and the personnel kept checking in others, right in front of me until I finally spoke up and pointed out their clear signs of ignoring me while patiently waiting to be checked in. Once checked in the gate the personnel kept chit-chatting and not managing which group is to board, being totally nonchalant, unorganized and behaving amateur-like . Very unprofessional and unlike the quality the Austrian Airlines brand otherwise provides. The crew on the plane are always fantastic and the best. What a shame the crew on the ground was so mediocre.

Flight delayed with no explanation. Boarding was confused (proceed to plane, go back to waiting area).

Last few years I didn't not have great experience with United Airlines.

Short flight. Bare bones and kinda seeming like an older plane. But got me there on time and that's what counts. Perfectly fine flight all the way from start to finish.

My Austrian Air flight from Montenegro to Vienna was delayed by three hours because their plane de-icer was broken and they had to wait for the sun to come up before the ice could melt. This meant we missed our United flight altogether. So I can't speak about United, but I was not impressed by Austrian Air. They made us check in two carry on bags for a 60% full flight, and the bags didn't find us in the US for ten days. The re-routing they arranged included an extra leg, a midnight taxi ride across New Jersey and New York, and a five hour sleep in a hotel. Not impressed.

Excellent flight. The crew was exceptionally attentive and organized. Attention to details is unmatched.

Great! They got my vegetarian meal right, flight was comfortable, they helped store my heavy luggage. Pleasant crew and flight staff.

Again the lounge boarding process were the only flaws. I was sitting comfortably in the overcrowded , under-catered business lounge at IST and got a notification in my phone that boarding had started. I rushed to the gate only to stand there an additional 5 minutes before boarding actually began. I could have enjoyed additional time in the lounge. At least they clearly separated business and economy classes in the boarding area so it wasn’t a total mob scene.

waited standing in security corral for an hour with no updates

Food was surprisingly good for airplane, crew was great, though announcements were sometimes hard to hear. Plane was nice (had great headroom, large screens and big dimmable windows). But seats were uncomfortable in economy (seat width was fine, but not enough shoulder room). I wish I could use my person Bluetooth headphones with screen( I think I could mirror it on my device, but didn’t want to keep tray table down to hold it up).

If I had a chance to rate Turkish airline in negative I will definitely give -100. Worst non professional attitude of ground staff at Istanbul. If I was a owner of Turkish airline I would definitely fire all check-in staff who was on duty for this flight. Rude attitude to all customers. Non availability of food options. Chicken and fish option was finished within 8 rows and only pasta was available (seat rows 25- last row). Seat Front glove boxes were ripped and all stuff was dropping on floor. Flight crew was trying to pacify the customers but this is sole responsibility of the manager who arranged / booked the food for this flight. He must be removed from this position as he has no idea about his job. It was worst flight during my whole life. Never booking again on Turkish airline.

Bussing in a major flight is idiotic. Cabin was too warm. Food was bland and felt old

Crew attendants attention to the travelers. Good food. I always fly with Turkish Airlines

Tv didn’t work and left the gate late but everything else was perfect.

Again poor use of old aircraft and old business class seats that show there age.

Service and food were very good, I liked it a lot. I liked the little gifts we all got , but I don’t think I’d fly on Turkish airlines to go to New York from Istanbul or from New York to Instanbul anymore. Flight is way too long.

We liked the comfort and seats. The crew was not very friendly nor did they check on us to see if we needed anything. Had to ask for water several times

It was very good. the food was varied and tasty, the movie was the same, maybe I would recommend changing the movie selection every month because my flight to Amsterdam was in September and I came back from Munich en October they are flights so long and we need something to see. But however I liked flying with United

A couple flight attendants in business class had bad attitudes and provided poor service. They did provide drinks or refill drinks. They talked to certain passengers for long periods of time and ignored others.

I especially enjoyed having a lightly packed flight which enabled me and my wife to occupy a three seat area with nobody in the middle seat.

Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.

The business class service was very good. The crew was helpful and the food was enjoyable. Boarding was well organized.

1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.

Flight attendants need to know their plane. Seated in first row yesterday. The seat had about a 1 inch recline that was not adjustable. I don't appreciate being awakened to raise a seat that can't go any further forward and such a small recline is either irrelevant or the plane needs to be repaired. Not the way to treat any customer and especially the ones who have paid that level of money for the seats.

The experience was good overall; however, my United Airlines Mileage Plus Account didn't reflect my flights to Houston from Newark. In essence, my mileage rewards points do not reflect my actual travel. This should be corrected.

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Plane arrived an hour before departure. Plane was completely boarded and ready for push back when they decided they needed to change a tire. 1 hour delay on the plane when this could have been done before we got on the plane.

Economy plus on a long flight with Lufthansa was wonderful. Service starts with a pillow, blanket, slippers and care package waiting on your seat. An it just gets better from there.

The Linate Milano flight was delayed. Landed at Frankfort at 12:10. Then took the bus on the tarmac and the bus ride was about 20 minutes due to the airport traffic. Got off bus went to passport control, used the kiosk scanned passport, took photo and finger prints and proceeded to wait in line. I asked the attendant that I had a connecting flight at 12:50 his respond was you have to ask the other travelers in line to let you go ahead. There should be a better system. Passed passport control and the gate was at Z69 to the other end of airport. Ran there out breath, I was last person to board due to a mechanical:electrical issue plane took off 2 hours later. Lufthansa need to a better job with international connecting flight. A 1-15 minutes is not enough considering the doors typically close 15 minutes prior to take off. So the window is reduced to 1 hour with all you have to go through with a slight delay it is not enough time. The crew on the flight was excellent and received exceptional customer service.

Loved the towel at the end. Service was frequent and perfect.

Horrible. Would not assist w hotel or new flights when Catania leg canceled

They left a little late, contributing to our missed flight.

Absolutely horrible. We missed both of our connecting flights from Frankfort due to the new border control lines. Lufthansa had us running and walking around the airport trying to rebook. They were not prepared to offer us a hotel room for the night, but finally relented when I said I was done with Lufthansa, most were not so lucky. I also put put of the blame in Kayak. You need to update which connecting flights you are offering to allow for more time to deal with the mess that is border control in the EU.

Cheapflights did not forward the payment for seat assignments, and my partner and I were separated and given center (B and E) seats. Will be requesting a refund.

Good communication via the app regarding the delayed departure. Uncomfortable seat for tall passengers. Could not straighten my legs.

roomiest flight in economy I've taken in years. Excellent experience!

The entertainment system was not working, they tried restarting it couple of times but it did not fix it. We were told to contact Lufthansa costumer service after the flight for some kind of reimbursement. When costumer service was contacted I was told no reimbursement for entertainment system malfunction per policy.
