My wife and I are taking several domestic Argentina flights in Y in the next few weeks, and I was hoping to have verification of what appears to be a huge difference between what LAN and AR publish as their baggage limits. I wonder if I'm misreading their respective websites.

LAN appears to allow 23 kgs of checked baggage and 8 kgs of carry-on plus a purse, laptop or diaper bag, per passenger.

In comparison, Aerolineas Argentinas appears to allow only 15 kgs of checked baggage and only 5 kgs of carry-on per passenger.

The difference between the 2 airlines seems too large, and I'm wondering whether anyone can either correct my reading of the respective websites, and/or advise whether these limits (especially AR's) are adhered to closely.

Thanks in advance!
