  This prospectus supplement relates to resales of our 6%
Convertible Notes due 2034 and shares of our common stock
issuable upon conversion of the Notes, plus an indeterminate
number of additional shares of common stock that may be issued
from time to time upon conversion of the notes as a result of
antidilution adjustments and as additional interest, in
circumstances described in the prospectus to which this
prospectus supplement refers.

  This prospectus supplement, which supplements our prospectus
dated July 2, 2004, contains additional information about the
selling securityholders.

  As used in this prospectus supplement, "the Company," "we,"
"our" or "us" refer to FLYi, Inc. (formerly Atlantic Coast
Airlines Holdings, Inc.) except where the context otherwise
requires or as otherwise indicated.

  You should read this prospectus supplement in conjunction with

the information in this prospectus supplement supercedes the

  Neither the Securities and Exchange Commission nor any state
securities commission has approved or disapproved of these

  The information appearing under the section entitled "Selling

supplemented with the following additional selling securityholder
and footnotes to the table:

               Notes                      Common     Percentage

(1)   Assumes conversion of all of the holder's notes at a
   conversion rate of 90.2690 shares of common stock per $1,000
   principal amount of the notes. However, this conversion rate
   will be subject to adjustment as described under "Description
   of Notes - Conversion Rights." As a result, the amount of
   common stock issuable upon conversion of the notes may
   increase or decrease in the future.

(2)   Calculated based on 45,333,810 shares of common stock
   outstanding as of June 30, 2004.  In calculating this amount,
   we treated as outstanding that number of shares of common
   stock issuable upon conversion of all of a particular
   holder's notes. However, we did not assume the conversion of
   any other holder's notes.

(3)   The amount listed represents additional principal amount of
   the notes beneficially owned as of November 29, 2004 by the
   selling securityholder, in addition to the notes beneficially
   owned by the selling securityholder as identified in the
   Prospectus dated July 2, 2004.  The selling securityholder
   has not informed the registrant whether or to what extent it
   continues to beneficially own the notes listed in the
   Prospectus.  If the selling securityholder continued to hold
   all of the notes as to which it has been the beneficial
   owner, the selling securityholder would beneficially own in
   the aggregate $24,326,000 principal amount of notes, which
   represents 19.46% of the notes outstanding.  Subject to
   footnotes (1) and (2) above, this aggregate amount represents
   2,195,883.69 shares of common stock that may be sold, or
   4.62% of common stock outstanding.
