Noticed that airline codes like QR (Qatar) and 9W (Jet Airways) don't show up when you highlight them. I understand that these aren't exactly the most major airlines, but they are airlines that show up in conversation, especially for redeeming on non-alliance partners.
Awesome. For future glossary input, is there a streamlined way to add airlines that might have been left out?
One update for something I found amusing: Within the definition for $mi$ek, one can click on the IATA code for Emirates. The code for SilkAir, however, is still unknown in the glossary. I just learned today that SilkAir will interline bags to most Star Alliance carriers, which makes my life easier.
You can't spell $mi$ek, or Mikel for that matter, without "MI" so that code has been added to the glossary - thanks for bringing it to our attention.
APD - Air Passenger Duty, an (unpopular) excise tax on all air travel departing the United Kingdom. Not applicable to itineraries with an international connection under 24 hours.
CPM is wrong: CPM: cost-per-mile. To determine this number, you divide the cost of the flight by the number of miles earned. For instance, a flight costing $259 which would earn you 2,980 miles roundtrip (MSP-FLL), thus a cost-per-mile of .087, or almost 9 tenths of a penny per mile. Often used in comparing airfares, the lower the CPM regardless of the destinations, the lower the cost to gain miles and of course status. 0.087 is almost 9 cents per mile, not 9 tenths of a penny (which would be 0.0087).
Additionally, we also often use cpm to mean "cents per mile." Similarly, cpp should be added for points.
All good, just click and read. Can add/subtract more with input, but CPP is on the board and CPM has been re-edited. Thanks to all crowdsourcing a glossary.
