must have you arriving no earlier than Sunday, and leaving no later than

  Saturday.

* Except as allowed by Policy, the search must not use filters that might

  exclude the least expensive fare.  For example, you may filter out

  flights with two or more connections, since Conservancy does not

  consider those reasonable.  However, you may not filter out specific

  airlines, or flights without WiFi.

Any widely-recognized airfare search site that lists results from multiple

airlines is acceptable, including sites such as [Orbitz](http://orbitz.com),

[Kayak](http://kayak.com) or [Hipmunk](http://hipmunk.com/).  The PLCs and/or

the traveler must submit the output (such as a screenshot or printout from

the browser) of a online fare search as part of documentation in airfare

pricing.  Make sure the output shows the least expensive fare available.

Travelers may book their tickets on different dates or a different site as

long as they used a qualifying fare search site to determine that the

booked flights are within Policy.

Any flights greater than US$100 over the lowest logical fare require

written pre-authorization by Conservancy.

#### Reasonable Flights

Conservancy asks that Travelers allow for flexibility with respect

to departure times during a desired day of travel, as well as longer

trips in order to reduce cost.  However, Conservancy does consider

flights with two or more connections as unreasonable and does not

expect Travelers to consider those flight options to be reasonable.

#### Excess Baggage

#### Out-of-Policy Bookings

All air travel not adhering to the above Policies are considered Out-of-Policy

and require written pre-authorization by Conservancy's Executive Director.

#### Cancellation Fees

Cancellation fees and other penalties incurred result of a change

of plans are reimbursable at Conservancy's discretion.  In general,

Conservancy shall reimburse such fees if the Traveler can submit a

valid reason for the change of plans.  Acceptable reasons include Conservancy

and/or the PLC canceling or altering the trip or unexpected delays

in flight connections.  In instances where these fees are incurred

without adequate explanation, Conservancy reserves the right to refuse

to reimburse the cost of the fees.

### Other Transportation

#### Ground Transportation

Ground transportation necessary as part of authorized Project trips

is considered to be a reasonable expense.   Public ground transportation,

such as taxis, shuttles, buses and municipal transit, are generally

the most cost-effective options and are the standard for eligible

ground transportation reimbursements.  All car rentals require pre-authorization

by the PLC or by Conservancy's Executive Director.  When car rentals

have been pre-approved, the rental of compact cars is encouraged;

mid-size vehicles are authorized when necessary (e.g., when compact-sized

vehicles are not available or the number of passengers or volume of

baggage makes a compact vehicle impractical).
