  • Next: each row is one exact trip for this departure (both dates with the year, the total and the time its price was issued); its exact-trip price link opens the live search for those dates and travelers, where the booking link and the current total are. Other durations or travelers are not priced here: Choose travelers and dates prices the requested trip.
  • Follow supplied links. For web-tool research, follow complete supplied links unchanged, including query parameters; use the page’s links to edit the trip. Constructed URLs may be rejected before reaching Axel. A completed fresh trip opens flight results first. Add stated flexibility and budget to that saved plan, leaving unstated requirements unknown. Edits create a new snapshot; use its results and review links.
  • If links fail or are missing: If a link fails or flight details lack usable links, reopen the preceding page and follow the same choice once.
