1-99 Flagship routes
100-199 Guam routes
200-799 Domestic Mainline
800-899 Asia routes
900-999 Europe routes
1000-2999 Domestic Mainline
3000-6999 United Express
7000-9999 Codeshares
182 does Denver-Frankfurt
143 does Denver-Narita
iirc 2600-2800 does charters or ferry flights but could be wrong on that
