Re: What is faster in baggage loading, bulk loaded or container loaded?

The big difference I see in bulk vs cans is in manpower. At YYC, 3-4 guys can do the front and back of a can-loaded 321 in about the same time as 6-7 guys on a 737. 6-7 people loading a 737 seems like overkill. US airlines I'm familiar with typically use 3-4 ramp workers per gate working a turn on ...

Re: Widebody vs Narrowbody Cruise Speeds

Well, they are faster than before. The 737 used to cruise at .74. Now they cruise more like .80. I think that faster NB speeds will only happen if they're optimized primarily for the longer sectors, which I don't see happening. The vast majority of 737s and A321s do 1-3 hour flights, and then pinch...
