ORD released statistics for Jan/Feb/Mar on Friday all together as the last US airport and as one of the last airport in the world! But...
I am not sure the report for January can be trusted. It claims 4.5% decline in passenger traffic and 4.9% decline in movements. I am aware about approx 1500 flight cancellation due to weather at the end of January (http://time.com/5516302/flights-canc...-cold-airport/) but is that enough for that big of a decline?
Here are reasons why I do not trust the data report issued by ORD:
1) last year ORD handled 83.3 million passengers and 863 thousand commercial operations (air carrier and commuter movements) which roughly translate into 96 passengers per plane. So if 1500 flights were cancelled ORD would lose approx 144,000 passengers. In 2018 in January handled 5,770,114 passengers which would mean with zero growth ORD would handle 5,626,114 passengers (this would be the number without 144,000 passengers), but in fact the report for January 2019 says 5,509,189 transported passengers! And I am not even assuming growth so something does not add up here!
2) ICAO monitor report for January https://www.icao.int/sustainability/..._March2019.pdf (based on ACI data) shows 3.6% growth in departures movements and 3.2% in departures of passengers. Also other source of ACI data reveal 3.2% growth to 5,952,588 passengers and 3.6% growth in movements. I know as a fact both agencies made mistakes in the past but this time I am leaning to believe ACI data.
3) The ORD report is odd, at least for a flight movements. All categories of domestic movements shows growth but total growth is negative? How?
As I have said, I am not sure who is right and who is wrong, but I would use ACI data for my statistical report. Maybe ORD will issue revised data soon.
What do you think about this?

The size of planes would factor but almost certainly not enough to account for the discrepancy.
