* Madrid (MAD) - Buenos Aires Ezeiza (EZE) - eff 01Mar18 - 24Mar18 - Equipment alternating between 787-9 and 787-8
Back in October, it was reported that MAD-EZE would be the first route that Air Europa would introduce its new 787-9's on with the type being flown on an alternating basis every other day with 787-8's between 01Mar18 and 24Mar18, presumably because Air Europa would be using its one and only 787-9 on the route during that time period.
* Madrid (MAD) - Buenos Aires Ezeiza (EZE) - eff 25Mar18 (?) - 787-9 definitively replaced 787-8

* Addis Ababa (ADD) - Sao Paulo Guarulhos (GRU) extends to Buenos Aires Ezeiza (EZE) - eff 08Mar18 - 5x/weekly
Ethiopian's service from Addis Ababa (ADD) to Sao Paulo Guarulhos (GRU) that started in 2013 was extended to Buenos Aires Ezeiza (EZE) on 08Mar18 on a 5x/weekly basis using 787-8's.
