2015-08-03 International WN flights at MEX
- WN652 SAT-MEX 11:45-13:45
- WN1810 MEX-SNA 14:40-16:25
- WN522 SNA-MEX 09:45-15:25
- WN318 MEX-SAT 16:20-18:20
Judging by the schedule, WN552 and WN318 were operated by the same aircraft. The same can be said with WN1810 and WN652.
Several flights that departed from SNA past 13:36 were eliminated through BTS since they overlapped with WN631's flight time, leaving N282WN and N273WN as possible aircraft.
N273WN stands out because of the long ground time between its recorded flights on BTS, so let's reconstruct its flight history.
WN315 SMF-SNA
Actual Departure Time: 06:01
Actual Arrival Time: 07:25

N273WN
WN1549 SNA-OAK
Actual Departure Time: 17:30 (can't be WN624/625)
Actual Arrival Time: 18:42

N273WN
N273WN also can't be WN552 because that would mean flying to SAT afterwards as WN318. Based on the information provided, BTS detected it departing from SNA later that day.
Based on my previous findings with the other SNA-SJD-SNA flights, I noticed that the WN planes flying internationally in the morning are those that arrived the previous night. If not, then it's usually a domestic flight with a few hours of turnaround.
I need
@Adam Smith to confirm this information because I can't verify it by guessing. If the plane was towed to the gate from a remote bay, then it's N282WN. If it arrived from a domestic flight, then it's N273WN.

N282WN
Both N273WN and N282WN cannot be WN624/625, so let's cross that off the list of their possible flights. Since N282WN departed at roughly WN764's arrival time, we can cancel out WN763/WN764, meaning that only N273WN could've flown that route.
If we reconstruct it with that in mind, we get this:
WN315 SMF-SNA
Actual Departure Time: 06:01
Actual Arrival Time: 07:25
Registration:
N273WN
WN763 SNA-PVR
Actual Departure Time: 09:02
Actual Arrival Time: 13:43
WN764 PVR-SNA
Actual Departure Time: 14:41
Actual Arrival Time: 15:36
WN1549 SNA-OAK
Actual Departure Time: 17:30
Actual Arrival Time: 18:42
Registration:
N273WN
But then you might wonder about WN624/625, both N273WN and N282WN couldn't have done that because of the conflicting times. The aircraft I'll be left out with from elimination could've possibly operated WN630/631 as well if they arrived before 08:15.
WN624 SNA-SJD
Actual Departure Time: 12:10
Actual Arrival Time: 15:19
WN625 SJD-SNA
Actual Departure Time: 16:17
Actual Arrival Time: 17:35
Using departures after 17:35, I canceled out N7729A, N242WN, N7728D, N708SW, N8607M, N249WN, N485WN, N489WN, N706SW, N203WN, N481WN, N429WN, N228WN, and N470WN because they had arriving times that conflicted with WN624/625's schedule.
Using arrivals before 12:10, I canceled out N263WN, N207WN, N273WN, N229WN, N418WN, N476WN, N933WN, N704SW, N8654B, N959WN, N947WN, N8640D, N492WN, N718SW, N206WN, N252WN, N904WN, and N7732A for similar reasons. This left me out with N452WN and N551WN as candidates for WN624/625. Here are their schedules at SNA on August 3:
WN1459 SFO-SNA
Actual Departure Time: 07:07
Actual Arrival Time: 08:27
Registration: N452WN
WN3659 PHX-SNA
Actual Departure Time: 09:32
Actual Arrival Time: 10:44
Registration: N551WN
N551WN's next activity at SNA was WN268 SNA-OAK, departing at 15:48 on August 4. Meanwhile, there was no recorded activity for N452WN.
Contrary to my expectation, this did not affect WN630 because the planes arrived way past 08:15, thus automatically ruling them out from operating WN631 as well.
@Adam Smith please confirm if my findings make sense.
