Flight & Hotel reservation email parser

Searches emails for flight tickets and hotel reservations. Builds a brief summary view of all your reservations over time.

Usage

1. Adding emails to the email database

   People store emails in various ways. Here we support the notmuch database (https://notmuchmail.org/) It is trivial to include maildir emails into notmuch with "notmuch new".

   For email programs with mailbox, mb2md (http://batleth.sapienti-sat.org/projects/mb2md/) can be run to convert to maildir, followed by "notmuch new"

   For Thunderbird, the thunderbird-notmuch-import.py script is provided, which finds the relevant folders automatically.

2. Building the report

   run with some email search keywords::

    $ python summary.py 'schema.org/FlightReservation OR ticket OR flight OR flug OR viaje OR booking OR confirmation OR confirmacion'
   

   It will give you some idea of what it finds, for example::

    2015-11-28 Flight HOUSTON, TX --> WASHINGTON, DC
   
    Departing 2015-11-28 19:10 
    from HOUSTON, TX  
    arriving 2015-11-28 23:05
    To   WASHINGTON, DC  
    Flight number UA1955
   

3. View report

   For an example report see "summary.html"!
