Hi guys, sorry for the late reply. I'm not able to make it to SES this year, so I've pointedly avoided this forum so not to get too jealous and/or sad.
Also we're no longer in the UK - moved back to Oz in August due to a new addition to the family who arrived at the start of November.
Still, better late than never I guess.
I always flew United and, despite what many here might proclaim otherwise, never had any trouble. My gear goes in a Burton 185 padded bag, though this is starting to get pretty beaten up after 7 or 8 years of global travel.
However the best arrangement I ever managed was with Michelle, where she shipped my gear home to save having to cart it (literally) around the world after the session. Sending it to Bomber on the way there just saves so many hassles it is worth the cost, and saves on potential excess baggage issues.
As for getting there and back, obviously fly to Denver, but whether you go direct with BA or via Washington or Chicago is probably just a preference thing (although Chicago does have a greater risk of weather issues, which we almost found to our cost one year).
Personally I don't bother with the flight from Denver to Aspen anymore. Just not worth the money or the risk that they won't be able to land and you'll have to go via ground transport anyway. For the cost of one ticket, you can hire a small SUV for a week, and although you won't need it during the SES itself, it's great for flexibility at the start and end of your stay. If you really want to save a little more, just do two separate one ways and pick up / drop off at Aspen airport.
Hope you have an enjoyable week and maybe we'll meet there in future years.
Cheers
Dan
