Target aircraft total: $1,566,960,000 $1,528,700,000 $1,461,080,000 $1,518,586,667(3)

Notes:

1. Collateral summary shown assumes that United elects to finance the aircraft with the earliest scheduled delivery dates from among the total aircraft of each type eligible to be financed with the proceeds of the Certificates.

2. Appraised value is the lesser of the mean and median base value of each aircraft as appraised by Aircraft Information Services, Inc. (“AISI”), BK

Associates, Inc. (“BK”) and Morten Beyer & Agnew, Inc. (“mba”). An appraisal is only an estimate of value and should not be relied upon as a measure of realizable value.

3. Appraised value as of July 2014. The aggregate appraised value as of September 3, 2015, after all such aircraft are expected to have been financed pursuant to this offering, is expected to be $1,494 million (using an assumed depreciation rate of 3% of the initial appraised value per year after the year of delivery of each Aircraft).

Aircraft Appraisals

United has obtained base value desktop appraisals from three appraisers (AISI, BK and mba)

Aggregate aircraft appraised value of approximately $1,519 million(1)

Appraisals available in the Preliminary Prospectus Supplement

Appraisals indicate an initial collateral cushion of 44.9% and 29.0% on the Class A and B Certificates respectively(2), which increases over time as the debt amortizes

Notes:

1. Total Aircraft Value as of July 2014 using the lesser of the mean and median of three base value appraisals for the aircraft. Assumes that United finances the first 11 out of 17 Boeing 737-924ER aircraft, the first of 4 out of 5 Boeing 787-9 aircraft and the first 12 out of 18 Embraer ERJ 175 LR aircraft scheduled for delivery from which United may select.

Collateral Overview

Boeing 737-900ER

Overview: The Boeing 737-900ER is the largest variant of world’s all-time best selling

737NG family of narrowbody commercial aircraft – 179 passengers in United’s standard two-class configuration (20 first / 159 premium and regular economy)

Strengths(1):

– US transcontinental range for the Boeing 737-900ER is better than the current Airbus 321 (without auxiliary fuel tanks)

– Lowest fuel consumption per seat/seat-mile cost of any twin-engine narrowbody

– 526 cumulative orders with 17 customers

– United and Delta, in 2012 and 2011 respectively, placed orders to replace Boeing 757s, marking a key win for the aircraft type

– Ease of remarketing to secondary operators due to sole source engine and commonality with other 737NG variants

Importance to United:

– United (and others) view the 737-900ER as a good replacement for the aging Boeing 757-200s—covers 96% of current 757-200 routes at significantly lower trip cost

Collateral Overview

Boeing 787-9

Overview: New generation long range aircraft with size similar to current Boeing 777-200ERs in fleet – 252 passengers in United’s standard two-class configuration (48 business / 204 premium and regular economy)

Strengths(1):

– First Boeing 787-9 flew in September 2013 and was delivered in July 2014 to first customer, Air New Zealand

– Strong order book expresses operator enthusiasm. As of June 30, 2014, there are 409 cumulative orders with 26 customers

– Approximately 20 feet longer and over 50,000lb higher MTOW than the Boeing 787-8 (33 more seats than 787-8)

– Composite fuselage is expected to reduce costs over span of aircraft’s useful life.

Overall the Boeing 787 is delivering up to 20% better fuel burn than the Boeing 767

– Improvements to the aircraft include: carbon composite fuselage and wings, health monitoring systems that allow the aircraft to self-monitor and new fuel efficient engines

Importance to United:

– Increased range of up to 300 nautical miles more than the Boeing 787-8

– Larger payload / passenger count (252 passengers)

– Fills gap between Boeing 787-8 and Boeing 777-200ER

Collateral Overview

Embraer ERJ 175 LR

Overview: Good level of commonality with other E-Jet family members – 76 passengers in United’s standard two-class configuration (12 first / 64 premium and regular economy)

Strengths(1):

– Combines improved operating economics with larger cabin for increased passenger comfort

– Better useful volume and cross-section than the CRJ family

– Current fleet of 211 aircraft delivered and a backlog of 167 aircraft, making a firm order total of 378 aircraft (as of June 2014)

– Demand for the Embraer ERJ 175 has picked up as major US carriers seek to replace 50-seaters with 76 seats; Both United and American have placed key ERJ 175 orders

– Long term, the Embraer ERJ 175 is expected to have superior seat mile costs to the Embraer ERJ 170 and better residual values

Importance to United:

– United will utilize the “LR” variant of the Embraer ERJ 175

– Will be used to replace 50-seat aircraft currently in the fleet

– Embraer ERJ 175 LR has a larger first-class cabin, increased fuselage and larger overhead bins than competing regional jets
