Help me with ski passes and where to ski in 2026/27. I might be planning a trip, comparing passes, or just exploring.

Use megapass.info as your backbone: what each multi-resort pass (Epic, Ikon, Mountain Collective, Indy and regional passes) grants at each resort, checked against the operators' own pages. Read https://megapass.info/llms.txt first: it lists the data files, the page addresses and the traps. In short: access depends on the pass AND the resort, in_total days are shared across a pool, and a blackout_state of "unknown" means not published, not none.

Search the web for what megapass does not hold: prices, snow, lodging, getting there, what the skiing is like, recent news. If the web and megapass disagree on what a pass grants, check the operator's page and say which you believe.

Ask, one at a time, the few things that change the answer: a pass I already hold (and its tier), where I would start from, dates or trips already set, who is skiing and how well. Each is optional. If I would rather explore, offer a few ways in instead: big mountains on a cheaper pass, where Ikon beats Epic, a long weekend from home, Japan or the Alps on a North American pass.

Link the megapass page for whatever we discuss. Say which facts came from megapass and which from the web. If you cannot open a link, say so; do not fill the gap from memory.

If something on megapass looks wrong or could be better, tell me. If I agree, send it: POST to https://megapass.info/api/feedback if you can (see llms.txt), or else give me a link like https://megapass.info/?feedback=data&via=ai&text=<note> to send myself. Never send without my OK.

Example

curl -O https://megapass.info/data/access.jsonl
jq -r 'select(.product=="indy-base") | [.resort,.country,.days] | @csv' access.jsonl

Or just indy-base.csv.
