A new HON Benefit was released just now, and I find it very valuable:

- Same-day changes free of charge in any fare class and any ticket, except Economy Light (ie Biz Saver is now possible to change)
- For flights within Europe only (no longhaul of course)
- Must be same route and same operating carrier (thats a bit of a pity on i.e. FRA-ZRH or FRA-VIE shuttles where LH and LX/OS rotate flights)
- Changes can be done in App or at Airport (Gate)

Personally, I really like it for my travel pattern…
