I would put this into the category of spending 13 hours in a sardine can. Many airlines are stripping valuable inches from economy seats to pack a few more in. Lantam have gone just about as far as they can although I suppose if they only allow passengers who are size 0 and 5 ft tall they can take out another inch or two.
Leg room is one thing. Seat width is another. Being cramped can be bearable if the service is good but 13 hours without a coffee was tough. We were in a row at the junction of two serving crews so at meal times needed to realize when they ask you what you want to drink you order juice, water and coffee because after they have served a meal they come from each end but do not quite meet in the middle and no amount of waving, pressing buttons etc made any difference. So you drink your coffee before your meal when it's hot or after when it's cold and in the cramped space that is a logistical problem.
In between we pressed the call button seeking a drink of any description and while she said OK we never saw her again until next meal time.
