IAT

An unusually roomy bag for an Indonesian carrier - maybe they've made the seat pockets larger to accommodate it?

The Indonesian Air Transport logo looks like an eagle that is rather depressed at having its body converted into a paper plane.

Iberia (extra large)

The only bag I know of that tells you (in Spanish) to fold towards you on one side, and away from you on the other. A simple but important detail ignored by the majority of airlines, leading to confused passengers and countless unnecessary spillages.

Iberia (1999)

Plain-and-simple bag manufactured by ACS (their logo is hidden in the gusset).

Iberia

A little more detail than the bag above: "For motion discomfort" in Spanish, English, French and German, and two lines along which to fold, instead of just one.

The brownish patch at the base of this bag isn't part of the design: it's Iberia's tea.

Iberia (2000)

Iberia are trying to reduce the red ink: no instructions on this new offering, and no bagmaker logo in the pleat either.

Iberia (2001)

The Spanish carrier has gone back to white, and has restored the folding instructions. Maybe a careful analysis of passenger-satisfaction data identified unfolded bags as a major cause of customer grumpiness? Looks like the 1999 bag above, but there's no ACS in the gusset, and the top is crinkle-cut.

Iberia (clearer)

This is one airline that thinks it is necessary to redo its logo every time it prints a new batch of bags. Not a complete revamp, of course, but a fresh layout, with slightly crisper lines and more white space in between the stripes. Maybe the designer didn't like the software used in the previous version, so had to redo the logo?

Iberia (larger)

Slightly bigger bag for those bumpier trips. The design has expanded slightly to fill the space better, and the instructions at the top are in a bigger type to make them easier to read in an emergency.
