We got there checked in and checked the bags. We went to the what we thought was f but was not. We happened to turn a corner with no signs. After going to the bathroom and sitting for 20mins, i thought it was weird no one was calling boarding 12mins before the flight. After talking to two people they said they left.

No paging for checked in guest, no warning of early departure.

Clean, efficient, friendly modern airline. Absolutely no complaints, especially given the rock bottom rate we paid!

No issues with the airplane or staff. Travelers to Argentina should know, however, that the airlines require proof of a ticket for leaving the country before boarding their flight. We had only booked one way so we had to book a bus ticket to Uruguay using our cell phones. It was very disconcerting. (Some very kind airline staff helped us with that). And even more so because no one at customs in Argentina asked for any return information! A last minute return flight booking at the gate was quoted at an outrageous sum.

Boarding was very disorganized and not on time. My seat assignment was changed upon boarding the plane. They had assigned 3 people to my seat which was an isle seat I had chosen upon purchasing my ticket 5 months prior. I was changed to a middle seat. They had an extra (makeshift) security check point on the actual boarding ramp. They made everyone open their carry-on bags and suitcases on folding tables just before entering the plane. They also took beverages bought at the gift shops, right before getting on the plane which was unusual. Overall ground crew was not very customer service oriented. In flight crew was better.

The entertainment system is exceptional. The food, in my opinion, has always been good. I've flown Lan Airlines since before the merger for at least a decade. The crew was efficient, in particular given the size of the flight.

Oddly, the seats were slightly less comfortable on this larger jet than on the LATAM flight from Santiago to Lima which was a smaller jet with one aisle and 3 seats per row.

Crew made effort to accomodate

Paid the surcharge to pick my seat. Check in changed my seat to emergency row. 1. I don't like the emergency row. I am not fluent in Spanish, the predominant language for BOA. They had to change my seat and changed me to an aisle seat. My shoulders are too wide and get hit by carts personnel. This was a Red Eye flight. So, between the bumps on the aisle and the storms we were flying thru, there was no sleep to be had. I also believe that BOA is reducing the pressure in the cabin. My breathing was like I was up in La Paz ( strained). This was a 7 hour flight. One of the wordt if not the worst, I have ever flown in 50 years of flying. Also, I do not usually gripe.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
