@ HIDDY :

So, yes, in all fairness, the app is probably not that important to those who fly once in a blue moon, such as your goodself.

BUT …..(efficient) apps have gradually become an extremely useful - and increasingly preferred - means of managing a whole range of everyday-life ‘tasks’ and general admin, whether that be travel-related / personal banking / online shopping / health management / navigation etc etc. In that sense, the genie is well & truly out of the bottle.

As to your frustration with the Lufthansa app : I’d say that the same applies to websites : if they are difficult to use, that is invariably down to a lack of investment, expertise, and attention to detail on the part of the respective business rather than the ability of the end user. The whole point is to make the customer experience easier - not harder ; something which many, many companies seem to manage perfectly well.

PS - the TK app is a pretty good one 👍
