Method & sources
Page scope
Compare six itineraries from three companies, with the dates behind months and fares. Fares are the starting prices on capture day; itineraries can change, so confirm with the operator before booking. The six-page snapshot of 18 September 2026 had no June/July dates. A separate check of both official direction pages on 22 October listed the same five June–July 2027 dates, across seven date–ship records; all seven were then marked Sold Out. The tables do not identify a direction for each record.

D4 · AFDJ and INHGA
AFDJ overview (captured 18.09.2026, 200): the Romanian sector = Baziaș km 1,075 to the mouth — the source of the 1,075 km hook, cited next to the figure; branches: Drobeta, Giurgiu, Călărași, Brăila, Sulina, Tulcea.

D5 · Site siblings
Cazanele Dunării (day trips: Orșova departures, fares, hours), Delta logistics (permits+boats), Delta birding (the monthly wheel): mutual links, separate subjects. Day-trip fares, boat timetables or monthly bird detail on this page mean overreach — please flag it.
D6 · Missing, on the record
June/July 2027 dates absent from the six-page 18 September snapshot (the 22 October official-page check found five distinct dates across seven date–ship records, all marked Sold Out; see Season); heat/crowds; the Viking ship and port; Ama fares; cabin comparison; Delta-mouth sailings; Cazane day trips; which day the water suits (read the bulletins, not this page).
Licence
The three-axis comparison, the schematic and the filtering logic are original; itineraries, fares and terms link to sources. Operator pages are versions, not guarantees: every figure carries its capture date — re-check at booking.
