I am flying domestic LATAM in Brazil in coach today. I am LATAM BLACK, and have unlimited cabin upgrade. I apply for upgrade online yesterday. Website showing I am at #3 in line, with first 2 being LATAM BLACK Signature. The website says I would be notified. Up until boarding time, no notification from LATAM website (upgrade success or fail). Upon door closing, there are at least 3 empty seats (not middle seats) in Premium economy cabin. I checked LATAM website, it said my upgrade was "not received". So what's the deal?

That appears to be true. I have two LATAM bookings, one issued by BA, the other by AS. It's an LA flight number and LA operated (issued by AS), but the website still doesn't allow any upgrade.




It's giving a "wrong" reason though, since marketing carrier isn't the issue - ticket issuer is.

At least seat reservation is working, and the website is already showing 2x 23 kg instead of just 1x 23 kg bag allowance.

Unsure if this has been asked before, but thought I'd ask: how do upgrades work for LA 800 from SYD to SCL? In particular there is a "connection" in AKL. Would I need to apply two coupons per pax for each of these flights or will one cover the whole thing? Additionally, which would have a better probability of the upgrade clearing: LA800 from SYD or LA 804 from MEL? I am planning on purchasing the Full LATAM fare since on a Oneway it's only about $100 USD more and gives me free upgrades and changes.

Technically they are correct. The flight is marketed and operated by LATAM Airlines Peru instead of just LATAM. This is also a concern I have as a LATAM Black booking flights to Brazil (and onwards from there) since most are operated by LATAM Airlines Brasil.

I understand your point, but I wouldn't think that this is the real issue. The vouchers wouldn't make much sense if they are only for flights from/to Chile?

It's using Flight Segments, so as long as you have in your reservation the flight SYD-SCL 1 coupon is used for both legs. Also that means that your upgrade will be cleared as long as there is space on the AKL-SCL leg.

Not really sure which one is best today, but I'd guess the flight from Sydney since it has more flights per week


It doesn't really matter. A couple of years after the merger of LAN and TAM the subsidiary was an issue due to different systems and processes.

Trying to upgrade using coupons on a flight segment marketed & operated by LATAM. But the ticket was issued by Delta (first segment is on Delta). So, website does not allow me to request upgrade...

Thanks for the data point. Appears to be the same issue as with my AS-issued ticket above. Not possible, unfortunately

Good news: messaged LATAM on X, and they were able to submit the upgrade request, even though the website does not allow it.

Bad news: just checked the upgrade list and (possibly because of the current status match promo) it seems clear you really need to be Black Signature to have a realistic shot at an upgrade...

One thing I hadn't realized: if you have a LATAM credit card, then you receive higher upgrade priority than all the others in your same elite tier who don't have one.

which route?
I am thinking about if routing through ATL will have a better chance than MIA for Black to receive an upgrade

In addition to restrictions that the ticket be on LA ticket-stock (and LA-marketed, and LA-operated), it would seem there are some restrictions on fare family or fare class?

I priced out a hypothetical LHR-GRU trip, and a LIM-CUZ trip.

LHR-GRU has Light, Standard, and Full.



LIM-CUZ has Basic, Light, and Full.



There's no reference to "Plus" or "Top." Perhaps this is a difference in translation?

My best guess is: they're saying their version of Basic Economy is not upgrade-eligible. For LHR-GRU, that's called "Light" (Blue). For LIM-CUZ, that's called "Basic" (also Blue). In which case, their naming convention is really quite confusing.

Or: they're still saying Basic Economy is not upgrade-eligible, but it's not even offered on LHR-GRU. Light is some type of 'standard,' non-Basic fare. On LHR-GRU, it's the lowest possible, and on LIM-CUZ, it's the second-lowest possible. In which case, their naming convention is more logical.

Anyone have any ideas?

I'm pretty sure that Plus and Top would be equivalent to Standard and Full. There is also an exception mentioned that the upgrades can be for Light on domestic or intra-South America fares (on tickets issued on or after May 4th 2023).

it is shown in the fare class column: "Request for UPG with segments" that allows you to request an upgrade.

As mentioned, I thought so too. But I couldn't be sure. In an ideal world, a carrier might make this more clear so their potential passengers aren't left guessing. And while it might not be too difficult for an astute passenger to divine LATAM's true meaning, it would be far easier for a diligent LATAM employee to just fix their own website.

Could you offer a link to the exception for light fares on domestic or intra-South America fares? I couldn't find it on the LATAM site, nor benefits webpage (relevant section reproduced below).

As Yollow said, just make sure that the fare you select is marked as UPG eligible. If you have already purchased a ticket, you can check its eligibility on the My Trips page. If it's not, you will see a message instead of the countdown to the check-in window opening

The detail for Light fare eligibity is on the website in Spanish.
