Farewell Chile (for the time being) as we head northwards overnight to La Ciudad de Mexico (CDMX). Scored a (bid for) upgrade on a Dreamliner, so should have a good night’s sleep before arriving at 5am at a head-dizzying 2,250m above sea level. Meanwhile, just negotiating through Santiago Airport has been a headache (second experience of this chaos this year) – just one person on immigration which caused a 1 hour queue and then a hugely dysfunctional and disorientating departure zone. Just breathe!
