Found it on B&H PhotoVideo at reduced priced and with transportation in CONUS & Canada included.
Took home my 350/70 refractor , three EP's , two prisms , one Barlow , one Beelink mini-pc plus various misc items up to 8 kg.
Even if it's 66cm in height was accepted as cabin baggage (thank you KLM for beeing sane and caring about kg not cm) and guess what: it fitted in the upper drawer without issues.
Got home and put in the 714/102 refractor - fits like a charm and still can take the EP's and one prism, not to mention all the side pockets perfect for filters , batteries, wipes etc.
