Find Cheap Flights from Chicago to Buenos Aires (CHI - BUE)

The service in Lester b Pearson airport was unprofessional and sub standard by your employee Manija Anwarzada and her shift workers. They did not help me when I missed my flight to Pittsburgh because of our late arrival from Frankfurt. She and the others were not there to assist and help stranded passengers. In fact a couple of the staff were on cell phones and not helping passengers. She finally told us we had to go downstairs to the hall since her counter was closing. After traveling from Algiers to Frankfurt then on to Canada it was a terrible way to end the day. These emoyess made a very long day even longer. I will never fly Air Canada again. I will say once I got through customs there were more professional people who did at least get me a hotel room. Your employee has left a very bad taste in my mouth for Air Canada!

Not much

We paid cash for business class seats on this flight and they were terrible seats. They were NOT business class, they did not recline and there was no leg room. Nothing offered to drink upon boarding. All they did was take economy class seats, three wide, and put a thing on the middle seat to hold drinks. It was terrible and we will avoid Lufthansa in the future, and we travel a lot.

Never got on this flight. We were never given an email to self check in, and we're unable to board 45 mins before at the gate coming frim anotthe flight. They overbooked this flight & sold our tickets, and then told us we couldn't get on flight. Now we are out $2500 buying new tix!

All the above. A simple check in email would have averted this problem. All the other airlines do this. We were under the presumption that we had to check in at airport when we didn't get check-in notice. Furthermore, they sold our tickets, so we're down $2500 and they doubled their profit. It would be hard for me to say I will use Air Canada or kayak in the future.

The crew is very friendly and accommodating. Food was decent.

Delayed three hours in Amsterdam then caused me to miss my connecting flight to Seattle. Then they only gave me the option of being late a day. On top of all that they lost my luggage. Time to retire that 767.

This was a very pleasant flight. The attendants were excellent. The plane was clean. The food was good for airline fare. The entertainment system made the flight go by better. Over all an excellent experience

The usual the leg room is not great nor is the space between passengers. But nothing horrible.

Well worth the upgrade price to purchase Business Class.

we no have entertainment for 8 hours. 20 TV's no worked in the plain

The crew was great as usual, and I always enjoy the unique selection of international film in the entertainment system.

That old plane was VERY drafty around the emergency exit. I can't remember ever feeling cold on a plane. Usually it's the opposite. But here was a consistent stream of ice cold air leaking through the airframe around the emergency exit. It was cold enough that I had to put several layers of blankets up on the wall and lean against them all the way home. In addition, my seat was so "well-used" that it provided very little support and often felt as though I was sitting on a bench. Not a pleasant experience.
