Have you 'collected' any new airports this year? (2019 - onwards)
 

2019:

BEG (Belgrade, Serbia)
ZAG (Zagreb, Croatia)
TUS (Tuscon, AZ)
ORH (Worchester, MA)
BOG (Bogota, Colombia)

For 2019, I am sure quite a few people can claim Paine Field (PAE), Everett, Washington. The terminal is new though in the distant past, it did have air service.

I keep going to the same airports. For 2019, PAE is a new one for me. I someday hope to add Rome FCO, which is a major airport. Also would like to add London City (LCY) and Billy Bishop/Toronto Island

Probably not super exciting for most folks but in 2019 I added DLH, AUS and MSY (the old terminal building).

I don't mind it when fun, old threads are brought up again, so thanks for doing that!

I had a good year for new airports in 2019 with 24. The most unique were certainly IOR and NNR in Ireland. LCY was probably the neatest from an airport standpoint, while DBV was the gateway for the best trip.

while I logged a number of Boeing Flight Test operations at PAE (1979-1982), the inaugural flight to/from LAS (4 Mar) on an Alaska (Horizon) E75 was my first commercial trip there

as far as other first-time airports in 2019, I arrived at Kenmore Air Harbor (KEH) on a Turbo Otter floatplane belonging to the namesake airline, and flew to/from Bozeman (BZN) on Alaska (Horizon) (E175 in, Q400 out)

2019:

BCN - Barcelona, Spain
TRS - Trieste, Italy
LIS - Lisbon, Portugal
GCM - George Town, Grand Cayman
LFT - Lafayette, LA
TUL - Tulsa, OK

Not an epic year.

2019:
PVG
MSY
TPE
CGN

I'm boring: just T2 (as opposed to T1) at ICN, if that counts. Only FAI the previous year.

MLE
MMB

USH Ushuaia Argentina
LYR Longyearben Svalbard

There should be a non-stop connecting these two airports or at least a connection at CPH. Keep writing to Scandinavian Airlines to make it happen! :P

I used Ushuaia for an Antarctic expedition in January, and Longyearben for an Arctic expedition in June. I wanted to be bipolar.

I'm off to a good start in 2020:

GSP (AA)
MGW: (9X)
UIN (9K)

2019 was also quite profitable for the new airport collector:
ABY (DL)
ACY (NK)
AEX (DL)
BGO (SK)
BKK (QR)
COU (AA)
CSG (DL)
EZE (AA)
GCM (AA)
HKT (TG)
ITH (UA)
JAN (UA)
KUL (MH)
MHT (AA)
MLU (DL)
MMX (SK)
OPO (IB)
PIR (US)
PVG (AA)
RAP (UA)
TLH (AA)
TLL (AY)
YQB (AC)

Slow year in this regard:

DPS
LHE
TSE
EVN

Scheduled:
