Aeroflot ICAO code mixup AFL and SMM

I have noticed that my schedule table, which is built by systematically downloading schedule information for the top 100 airlines (from CountAllEnrouteOperations) contains every flight from Aeroflot twice, but under different ICAO codes: AFL (real) and SMM (false)

This seems to be a bug in the reference data of FlightAware.

offtopic Simferopol de-facto is RU :point_up:

Im not sure where the correlation is coming from. Could you provide any other info on the SMM flights?

Fligtaware contains a lot of mistakes regarding flights of Russian airlines…

For example, in app reviews you can notice very disappointed Russian users:
“… wrong an airlines, wrong a flights …”

Use this code with ICAO code 'AFL ’ and see what you get:

# ## AirlineFlightSchedules

import requests
from json import loads, dumps
from string import ascii_uppercase
import time
import dataiku
import pandas as pd, numpy as np
from dataiku import pandasutils as pdu
import wait

t1 = int(time.time())
t2 = int(t1 + 3600 * 24)

# --- GET SCHEDULE ---
def get_Schedule_by_Airline(airline):
    # -- Details for the API
    username = "funkmeister380"
    list_of_flights = []
    next_offset = -1

    payload = {'start_date' : str(t1), 'end_date' : str(t2), 'airline' : airline, 'exclude_codeshare' : 'True',
        'howMany':'150', 'offset' : '0'}
    response = requests.get(fxmlUrl + "AirlineFlightSchedules",
        params=payload, auth=(username, apiKey))
    kr = 'AirlineFlightSchedulesResult'
    # -- parse the results
    if response.status_code == 200:
        r2 = loads(response.content)
        if kr in r2:
            list_of_flights = r2[kr]['flights']
            next_offset = r2[kr]['next_offset']
            print "Error executing request"+ response.content
            next_offset = -1

    while next_offset > -1:
        payload['offset'] = str(next_offset)
        response = requests.get(fxmlUrl + "AirlineFlightSchedules",
                                params=payload, auth=(username, apiKey))

        if response.status_code == 200:
            r2 = loads(response.content)
            next_offset = r2['AirlineFlightSchedulesResult']['next_offset']
            #print next_offset
            if next_offset == -1:
            print ("Stopped with offset" + str(next_offset) + response.content)
    if len(list_of_flights) > 0:
        flights_pd = pd.concat([pd.DataFrame(t, index=range(len(t))) for t in list_of_flights]) # for schedule results
        print "-------------"
        print airline
        print flights_pd.groupby("destination").size().sort_values(ascending=False).head(10)
        return flights_pd.drop_duplicates()
        print "No schedule for Airline "+airline

Took some digging, but I believe we found the issue and corrected it. Thank you for the heads up on it.
