Thin Air, Then Sea Level

Special Notes

Several things on this route follow a permit office, a season or a sailing calendar rather than our preferences. Here they are, told straight.

• Bookings are not open — we take no orders and no deposits. Four things have to close first: a departure calendar that satisfies every date constraint at once; the Lhasa sourcing, including the oxygen-equipped hotel; a definite answer on the Tibet permit for visa-free arrivals; and contracted cabin inventory on the river with a sailing date that lines up with the Lhasa flight. Tell us your dates and we will write to you when it opens.
• The permit question, first — every guest on this route needs a Tibet travel permit in addition to their entry route. Whether a guest who enters China visa-free, holding a passport with no Chinese visa page, can obtain that permit is not settled in our records. All six visa-free markets ride on it. We are not selling this route on the assumption that the answer is yes.
• Permit lead time — The permit pre-review requires at least 15 days before departure, so orders within 15 days of departure are not accepted in any market. Note that our approved payment terms set the balance at 14 days before departure, one day later than the permit deadline. The two do not align; the permit deadline takes precedence, and how payment is scheduled against it is determined before bookings open.
• The October to December 2026 season — the Lhasa section is arranged from April to October only, and the river ships end their 2026 season on November 27 and December 7. On an 18-day plan, any departure after mid-October crosses into November. Those two windows together leave effectively no departure date in October to December 2026 on which the whole 18 days runs inside every window, so this route is not sold for that season. As designed it sells in the April to October window.
• Altitude and what is not yet in place — the plan gains 3,150 metres in one flight on day 8 and then holds a rest day with nothing on it, one item per day after that and a descent by river rather than a second flight. That is the design. What is not in place is the equipment side: the oxygen-equipped hotel this section rests on is not contracted, so we do not describe an altitude safeguard as if it existed. A pre-travel questionnaire on heart and lung history is being written and is not finished.
• Departure dates — four constraints have to be computed together rather than one at a time, and until that is done there is no departure calendar. Day 2 is never a Monday, when the palace closes. The Xi'an day never falls in the October 1 to 7 holiday week. The Lhasa section runs April to October. The embarkation day is fixed by the ship's own sailing days, checked sailing by sailing against the operator's current calendar rather than extrapolated from a weekly pattern.
• Transport not yet verified — the cabin class on both high-speed rail sectors and on all three domestic flight sectors is not set, and the three flight sectors have not been checked against the current season's timetable. Each is stated in writing in your quote, and none is quoted before it is verified. A blank cabin class reads as the highest grade, so it is never left blank.
• Passports — the UK, most of Europe and Canada enter visa-free for stays days, and Australian and New Zealand passports have the same 30 days. We check the 18 days plus any further days in China against that window order by order, which leaves 12 days of headroom at most. The current policy runs through December 31, 2026. Departures on or before December 14, 2026 finish inside the window, and later ones are quoted only after an official renewal. US passports are not on that list and this plan is longer than the ten-day visa-free transit policy allows, so a US guest would need a Chinese tourist or business visa plus the permit. Whether US guests belong to this route at all is under commercial review, and no US order is taken meanwhile.
• Entering on the transit policy — guests who entered China under the ten-day visa-free transit policy cannot take this trip. Eighteen days exceeds that policy's permitted stay and its permitted areas do not include Tibet. We say so before payment, and we do not look for workarounds.
• Confirmation and changes — The confirmation-time commitment and the change and refund terms are being settled with our ground partners and the ship operator. Until they are, each quote states in writing its own confirmation deadline and its change and refund conditions. Structurally this route holds three domestic flights, two rail sectors, a fixed-date sailing and a permit with a 15-day pre-review. A date change touches all four at once, and the sailing day is the least movable of them.
