Hi!

I checked expedia.com for routing rules and comes out:

MPM - AT 4506 VIA NORTH ATLANTIC
INDUSTRY FARE TYPE - XPN - INSTANT PURCHASE NONREFUNDABLE
PFCS MAY VARY BY RTG
ROUTING MPM MPM TRVL PERMITTED

I see from other searches I guess:
Routing 1 : non-stop
Routing 3: one connection (e.g. DTW-ORD/DFW-STL)
But what is MPM?

Also, concerning transfer, it said:
TRANSFERS - 2 INTERLINE PERMITTED OUTBOUND 1 INBOUND 1 FURTHER RESTR APPLY SEE TEXT RULE UNLIMITED ONLINE PERMITTED

Then means basically I can connect within US as many times as I can.But will there any restriction for that?
(e.g. will I not allowd to go from east/central city to west coast gateway?)

Thanks and happy travel!

It means Maximum Permitted Mileage.

Someone else can define further since I dont have the exact definition.

To be honest, I'm not sure exactly who has done this (maybe IATA) but some organization has determined what the maximum permitted mileage is for a given city pair. When an airline quotes a mileage fare (which is generally higher than other fares offered by the same airline, b/c it offers more flexibility in routing and offline connections, etc.) that fare is valid for journeys from origin to destination for up to that mileage level.

You can then go over the MPM (I think by up to 20%) for additional surcharges.

Answer to your question, unfortunately, I don't know. The way I read it, you're only able to make 2 connections (between other airlines) but as many connections as you want on whatever carrier this is.

My guess (and it's just that) is that you wouldn't be able to go from an east coast city to a west coast gateway b/c this is an instant purchase type fare, so the MPM is probably very close to exactly the shortest distance between your two points, e.g., if this is a CMH-LHR fare on UA, the MPM is probably such that it is almost exactly the mileage CMH-IAD-LHR, and if you wanted to go through ORD, you would pay the mileage surcharge.

Good luck (although I think this stuff is sort of fun - I don't play chess, I play fare construction games).

Re: MPM

Does anyone knows it means real flight mileage or mileage count for FF A/C?

e.g. a flight DTW-ORD is only 2xx miles but will credit my account as 500miles.
For MPM, this flight will count as?

Thanks and Good day!

Real mileage,

MPM is, I think, actual miles plus 20% (to allow for connections). Has nothing to do with Freq Flier Miles.

To get an idea of when an MPM fare can be better to use, compare UA and AA from Atlanta to BKK. UA gives you all of the connecting points, AA leaves it up to you (but you must stay within the MPM). I got ATL-BKK one time routed ATL-DFW-NRT (on AA), NRT-BKK (on JAL) BKK-NRT (on NW) and NRT-ORD-ATL (on AA).

Never have quite understood, though, whether the preponderance of the tkt has to be on AA, for this example, or what.

This wkend I'm flying ATL-CPH. On DL, you could go (all on DL flight nos) ATL-CDG-CPH. But for the fare I'm flying (MPM), it's allowing other connx points (I'm actually flying ATL-MAN (DL) MAN-CPH (SK) CPH-ARN (SK) ARN-JFK-ATL (DL).

That means if the fare base allow me 4506 MPM, I can route a trip with max mileage
A. 4506x(1+20%)=5407mi
OR the route I select x(1+20%) must not exceed 5406?

Sorry but my ord-bos connection just exceed the MPM by 2xx miles :O

Thanks again!
