Unique Revenue Approach Non-traditional markets Aggressive capacity management Ancillary revenue Own reservation platform Closed distribution system Pricing power

Non-Traditional Markets Small, underserved (and sometimes unserved) markets Value proposition: Nonstop Local airport (avoid multi-hour drive) Big airplane Low, low fares Third-party sales Little to no competition Stimulation of previously overlooked markets

Avg. daily scheduled flights by month(1) Aggressive Capacity Management 2008 2007 2009 July 2008 High Fuel Price (1) Published schedules thru June 2010 2010E March > 8 block hours Sept ~ 4.5 block hours (1)

Ancillary Revenue Air-related charges, $29/pax in 2009, a la carte pricing (bags, seats, etc) Third party products, $4/pax in 2009 3.5% of 2009 revenues, 16.4% of pre-tax income Merchant model – wholesale price from hotel or rental car, we set the retail price Corporate focus on driving significantly more hotel sales Hotel room-nights up 24% 2009 over 2008 to over 530K Not just an airline

Own Reservation System Vast majority of airlines use system owned by third party - GDS (e.g. Sabre) or new gen LCC system (such as Open Skies) Software enhancements driven by consensus Encourages commoditization – all can offer same products We can offer a differentiated product Uniquely (and quickly) tailored to meet our changing needs Key to our ancillary revenue strategy Only airline system with capability to bundle hotels and cars using merchant model and with the ability to handle any unbundling fees we can conceive Allegiant Information Systems (AIS) - key differentiator

Distribution Can only buy Allegiant air service from one source...Allegiant! Maximizes eyeballs of highly desirable customers on one website and creates revenue opportunities from: Sale of third party products Better CRM opportunities Advertising Very focused on monetizing brand value For air, lowest costs lets us charge lowest fares (with or without competition) – it’s the easy part Key is to leverage the brand equity we have developed – 97% approval ratings – and drive other revenue through our portal www.allegiantair.com Closed distribution is critical

2010 Agenda Hawaii and 757-200 Fleet $25mm share repurchase authority – YE09 cumulative buyback $42mm Long Beach (California) – 2 slots recently awarded Grand Rapids new “small city” base – April 2010 Orlando International – 10 routes Buying 20 MD-80s from SAS Plan to add 15 aircraft in 2010 and 2011 Five aircraft to be parted out 2009 EBITDAR(1)/avg aircraft ~ $3.6 mm or approx cost of an MD-80 Recent events (1) See Appendix for GAAP reconciliation of EBITDAR (1)

Hawaii Largest major US leisure market untapped by Allegiant Significant ancillary revenue opportunity Large hotel & rental car opportunities from longer passenger stays Significant fee opportunities from longer stage lengths No service on planned routes Existing and forecasted fares much higher than what we plan/require “But no one makes money flying to Hawaii” – people say the same thing about Las Vegas, where we make a lot of money Good time to enter the market Airline capacity down substantially Hotels need lots of help... we can give them lots of help! Why Hawaii? Why now?

757 Program Best Hawaii aircraft Can reach Rocky Mountains 200+ seats Acquisition cost enables same flexible capacity approach as MD-80 Matched set of six high-spec, excellent-condition aircraft available Limited downside – if targeted expansion market fails, we can profitably put these to work elsewhere Asset values at trough in the cycle 757 NOT a replacement for MD-80 MD-80 best in class for Allegiant routes within its range 757 opens complementary opportunities MD-80 routes still represent overwhelming majority of future growth opportunities Why 757s? Why now?

Network Evolution Geographic diversity Destination Markets 2Q10 depts Y/Y change depts Las Vegas 39 35.0% 0.2% Orlando 30 23.4% -6.9% Phoenix 20 13.0% 28.9% St. Petersburg 20 13.2% -7.6% SoCal 11 5.9% 56.3% Other 18 9.5% 6.1%

Growth – Same Store Departures True same-store departure growth for a given month excludes: Routes flown in this year but not prior year or vice versa Routes flown for a partial month in one or more of prior or this year Room for capacity upside in 2Q10
