Pardon me if this is a re-posting, or not considered earth-shattering to those who monitor the schedules frequently, but I found it very interesting that both AR and AA have loaded extra daily services each on the MIAEZE legs, and each one being a DAYLIGHT flight at that! I mean, they literally both seemed to load the extra flights within 20 mins of each other.

AR1304 EZE0845 – 1655MIA 343 D
AR1305 MIA1900 – 0500+1EZE 343 D
What I find intriguing is that AA is sending their largest aircraft (that is, pre-77W deliveries) with an F cabin on the daylight flight, when arguably the premium traffic/demand normally opts for the overnight flights given that timing and scheduling is more convenient. Even though the 772s will be reconfigured to a 2-class (J, Y) layout sometime later on down the road, certainly AA will be flying F seats around on these flights for a little while. Why did they not start out with a 767? Especially since MIAGRU doesn't even go year-round with its daytime flight, and I am pretty sure that has always used a 767.
Also interesting to note just given that both carriers are not in the best financial conditions at this time, but are obviously bullish on protecting marketshare on this route, often rumored to be highly lucrative.
