If you go to Argentina, fly with any airline, but NEVER Aerolineas Argentinas.
On our flight from Madrid to Buenos Aires, they lost the luggage(delivered it 36 hours later!) and my camera was stolen from the checked-in suitcase. But worse was to come for the return flight:
We tried to return from Buenos Aires to Madrid on 8 January 2008. The flight was delayed - initially - by 16(!) hours, from 2300 to 1500 next day because one of the pilots failed to show up for work. This meant for everyone re-entering Argentina(queue for passport control), wating for the luggage to be unloaded(another 1.5 hours wait), queuing to get a hotel voucher(another 1 hour), and then a 90-min bus transfer to a hotel 60km away from Buenos Aires. We eventually got our hotel room by 500 am. We were told to await the bus back to the airport at 1100 am(i.e. 6 hours later). It arrived only at 1430, by then the flight had been postponed from the originally planned 1500 departure time to 1900. Later on, it was shifted again to 2100. It eventyually took off just before midnight. Cabin was initially not airconditioned, leading to unbearable sauna-like heat for the first hour or so.
Worst of all, not a single word of apology from the captain or crew for the 24 hour delay. To add insult to injury, the captain did his usual spiel at the end with "hope to welcome you onboard an Aerolineas Argentinas flight again", which appeared to be a deliberate affront to a full cabin of enraged and suffering passengers
In Madrid, onward flight to Frankfurt was missed, causing another 5-hour wait. Rebooking of flights for all passengers with onward connections at the local Aerolineas desk was a chaos, causing tumultous scenes. There in fact were ealier flights to Frankfurt with other airlines, but since none of these would do any business with Aerolineas Argentinas, we were - once again, as had been the case for the past 36 hours - de facto "hostages" of an atrociously badly managed and incompetent airline.
