Final part of the International T-100's for August, which is the Caribbean, many routes are 1 weekly or so, so I am going to focus on the multiples that reflect a larger population to work with.
PUJ - DL only fly 1 weekly and performance was pretty flat year on year, uptick in gauge, but a very small uplift in pax, leading to a 9% drop in load factor
B6 - fly roughly 4 weekly but the issues in the DR were exceedingly clear from these results
Load Factor: 68.5% [93.8%]
Flights: 36 
Seats: 5,832 [5,100] 7.4%, 5.1%
Pax: 3,993 [4,784] 7%, (26.9%)
After a great 2018, B6 had set themselves up for an expansive 2019, unfortunately the events in DR destroyed that, and this turned into a horrible set of results from them, while they increased gauge and a slight increase in frequency, the market collapsed 27% during the month.
HAV - only including this because it's interesting for many people, 52.2% this month. Again, no surprise this was cut.
STI - B6
Load Factor: 79.7% [87.2%]
Flights: 107 
Seats: 17,910 [11,910] 7.6%, 25.9%
Pax: 14,271 [10,386] 28.4%, (1.1%)
Not as pronounced as PUJ, but STI still suffered a bit, gauge increase here too and a big volume increase, but a 1.1% market decrease was a bit tough. Given the hike in capacity not the worst, but I suspect B6 were hoping for better.
PAP - B6
Load Factor: 92.5% [88.3%]
Flights: 36 
Seats: 5,808 [5,400] 7%, 0%
Pax: 5,374 [4,767] 0%, 11.3%
Decent set of results here for B6, 7% increase in gauge as the bigger 320's came on stream. it was well rewarded with a 11.3% market increase as pax went from 132 to 149 (which would be 100% load effectively for the regular 320's)
SDQ - B6
Load Factor: 86.9% [94.4%]
Flights: 106 
Seats: 18,820 [9,858] 11.9%, 35.8%
Pax: 16,346 [9,302] 38.8%, 4.3%
One of those that a 7% load drop doesn't tell the full story, 36% increase in volume, coupled with a 12% increase in gauge is a huge amount of capacity to put through the market, but.. they did exceedingly well, by covering the volume increase and 4% of the gauge, avg pax count 148 to 154, which would have been too tight for the regular market. 44 of the 2019 flights were on all core 321's...
BDA - Combined 90.7% 15,900 [15,760] 90.1%
Load Factor: 90.9% [91.9%]
Flights: 62 
Seats: 9,348 [9,300] 0.5%, 0%
Pax: 8,494 [8,548] 0%, (0.6%)
Pretty flat, slight uptick in gauge coupled with slight drop in market led to a 1% decline in loads.
Load Factor: 90.5% [88.1%]
Flights: 62 
Seats: 8,184 [8,184] 0%, 0%
Pax: 8,494 [8,548] 0%, 2.6%
DL wins the growth battle, however they are using smaller aircraft than B6, that said 2.6% market growth will do just fine..
SJU - B6, ok, I know PR is counted as domestic by T-100, but Massport I swear report it as Caribbean, so hence I have moved it to International.
Load Factor: 83.7% [88.3%]
Flights: 243 
Seats: 38,130 [27,294] 3.9%, 24.5%
Pax: 31,910 [24,096] 25.9%, (1.4%)
The recovery continues, say what you want about the state of PR and it's economy, people still want to fly there from BOS and in decent numbers too, the move from close to 3 daily up to almost 4 daily, pretty much paid off, with the pax count covering at least the increase in volume, but not quite covering the gauge increase too, the difference is 2 pax per flight, so roughly 480 folks... can't see B6 being terribly upset about that.. Solid results..
Last but NOT least..
AUA - DL fly once a week, so I am ignoring their numbers here.
Load Factor: 89.2% [89.6%]
Flights: 82 
Seats: 15,692 [11,772] 21.1%, 3.8%
Pax: 14,003 [10,553] 3.9%, 20.8%
Ahhh the memories of April when i got to visit such a beautiful island.. not sure I will have the money to go back, but... if I do, I will. But I digress. I call this the not quite home run, you know, the one that bounces off the top of the green monster and back into play.. you've all seen it. Huge uplift in gauge of 21% with 87% of flights on some form of 321 but mostly all core, with the odd weekend mint thrown in (sadly the T-100's don't go to tail level on this route to determine which was which). 4% increase in volume and they got so close to filling the entire gap, but just fell short to bring the avg load down by 0.4% Avg pax went from 135 to 171... Folks LOVE AUA!
So there we have it, August is in the books, Once September is out next month, I will do a slightly different analysis of the summer season from May to September to see how folks got on during the whole thing...
Thanks for the kind comments and reading all of this, it's only worth doing if that happens.. I'm going to be out of pocket after this week because I'm off to MIA on Friday for a cruise on DL no less (rather than AA).
Thanks for the information. Have a good trip!
