My ears were getting warm as I arrived, so I checked the FT forum. Till, thank you for the compliment. I'll try and be worthy of such accolades.
RE: LH-RIMOWA CARRY-ON
1. As stated above, Lufthansa has carried a LH branded Rimowa marque of luggage for many years now. Many of the features in this luggage are quite unique and practical versus the standard Rimowa lines, worth investigating when considering luggage.
2. LH does then favour passengers using LH branded luggage, as well stated above. But passengers carrying said luggage are expected to know the rules and regulations, and pack LH carry-on cases within reason. Overweight ( luggage, not the passenger ) carry-on, with squeaking wheels, and underwear and even lederhosen flapping outside will probably earn you a second look and the feared scale. If you are using LH branded luggage, perhaps even a court marshal.
3. There is no rule that states today your LH luggage cannot be gate-checked. My LH alu attache was once with my laptop, and there was nothing negotiable in the demand from the counter, as the agent wasn't in the mood that evening. The flight was 100% full, and perhaps coincidentally, that was the one time I flew economy.
So one must be prepared these days to have carry-on, even if with newly purchased Private Jet or Titanium model, placed in the LH cargo hold.
4. Important ! If Nr. 3 happens, a word of advise: Never argue with a Lufthansa GA or FA. Especially if they are in uniform.
If you do you will notice that all time stops immediately, all sounds cease, you get the dreaded stare from everyone, you become embarrassed, and then suffer cardiac arrest. Perhaps even worse.
That being said, in reading this post, the smaller sized case ( 55 x 40 x 20 cm ) would be best suited. This would be my choice between the two.
Bordkoffer is an older term, used previously with a small hand-carry only case. I used one for a few years until it morphed into the current business case with wheels. My right arm then returned from somewhere near my shoe to it's original length. Rimowa cases today come in 2 and 4 wheel versions ( 2-4x rollern). I can be confusing when ordering online, so I do think it best to try and find a local store to try each case on for size, if you will.
Between inch measurements, centimeters, or the product code Nr., I would try and verify the code Nr. and use that if making a purchase. I hope this is helpful.
