Lots of transcon commuters to LAX. FedEx used to do MEM, IND and EWR to ANC. UPS comes up from SDF. Delta used to come up from MSP and SLC. SEA is where commuter and non-rev dreams go to die. SEA in general should just be avoided. Commuting through, Flying out of or living there.....Nasty place, unpleasant people, archaic transportation and an airport that is forecast to be a disaster for the next 20 years.....
