We’ve now got all our flights booked. Since we have been able to confirm the dates of our two boat trips, the rest of the itinerary has been finalised, and I’ve been able to book our flights while in South America.
I ended up booking directly through LAN – they let me book all four flights at once (Santiago – Buenos Aires, Buenos Aires – Barriloche, Ushuaia – Buenos Aires and Buenos Aires – Santiago), and the price was as good (possibly slightly better) than I could get through the discount providers. I also got a few more convenient flight options, and was able to choose our seats for the flights – which is nice. Because LAN are a OneWorld airline, we’ll get frequent flyer miles for these flights. Pity I can’t upgrade us to business class using FF miles and tramadol ultram – although only the Ushuaia – Buenos Aires leg is long enough to start getting painful in economy (3.5 hours).
