Thanks, Jeff. I would like to first thank our customers for choosing United. We are working everyday to provide you with reliable service and a flier-friendly experience to the destinations you prefer. We appreciate your business throughout 2014 and we look forward to serving you again this year. In the fourth quarter, our unit revenue increased 0.4% slightly higher than our expectations. As we described previously this result was negatively impacted by a 1.5 point headwind due to fourth quarter 2013 interline ticket reconciliations. As this was one-time in nature, it will not reoccur in the subsequent quarters. Our three-pronged revenue initiative focused on revenue management, network planning and our express operation continues to deliver solid results. In the fourth quarter we re-banked our schedule in Denver and Houston and we will re-bank our schedule in Chicago in the first quarter. The initial results of our re-banking have met our expectations and connecting yields in Denver and Houston have increased year-over-year. By expanding our connection opportunities in these hubs, we are able to improve the mix of originating and connecting customers. We more seasonally shaped our schedule in the fourth quarter by reducing flying during the lower demand shoulder period and expect to increase flying during the higher demand summer period. These changes contributed to the unit revenue results in the Atlantic entity which grew approximately 7% year-over-year. We anticipate the full year 2015 effect across the network to increase both unit revenue and margins. During the quarter, we also made good progress consolidating frequencies as we flew larger gauge planes and reduced our alliance on 50-seat aircraft. Frequency consolidation provides several benefits to the airline as it reduces cost, improved reliability, and expand the product offering by providing more premium seats and upsell opportunities. In the fourth quarter, our gauge increased on average by 4% while departures decreased by 6%. We will continue to execute on this initiative throughout 2015 and expect our gauge to increase 6% on average for the full year as departures decrease 4%. Examples include the Denver to Minneapolis, O'Hare to Cleveland, O'Hare to Philadelphia routes. We continue to overhaul our express operation by reducing the number of 50-seaters in our fleet. In 2014 we removed 39 50-seaters and introduced to 33 Embraer 175 76-seat aircraft. These newer larger gauge airplanes have been very well received by our customers and we have seen an increase in ancillary revenue since their introduction. Ancillary revenue per passenger earned on an E175 is 15% higher than on the 50-seat aircraft they are replacing largely due to having 16 economy plus seats and 12 first class seats. This regional fleet overhaul will continue into 2015 as an additional 71 50-seaters will exit the fleet by the end of the year with 49 additional E175s entering the fleet. Some of these E175s will also replace Q400 turboprop aircraft which will begin to leave the fleet this year. This transformation has had a positive impact on the reliability of the regional operation. As our fourth quarter controllable completion rate improved year-over-year with a better product offering and a more reliable service. We expect these actions to generate additional revenue and unit cost benefits in 2015 and beyond. In the fourth quarter, our corporate revenue portfolio increased by 4% year-over-year with strength coming primarily from the technology and healthcare sectors. We have been monitoring the impact of lower oil prices on our energy related corporate traffic. In the fourth quarter, we noticed a small impact and we are working closely with these corporate partners as they begin planning travel for 2015. Ancillary revenues continue to grow in the fourth quarter increasing approximately 10% per passenger and we achieved our goal of $3 billion of ancillary revenue in 2014 despite capacity growth being 1.2 points below our plan. With family plus revenue per available Economy Plus seat was up 22% in the fourth quarter compared to last year. To date we have installed Wi-Fi on 451 main line aircrafts and begun installation on our regional fleet. Our streaming video product is now on 194 aircraft and customers give it very positive reviews. Wi-Fi installation will be largely complete by this summer with streaming video installations complete by the end of the year. For the first quarter, we anticipate our unit revenue to be essentially flat with several factors contributing to our revenue performance for the quarter. First, our unit revenue outlook is impacted by a shift in revenue from MileagePlus redemption tickets out of the first quarter. This is a result of having new, more accurate data which allows us to recognize passenger revenue in the period in which the customer redeems miles per travel. This does not impact cash or our full year revenue outlook but will provide a headwind of approximately $75 million or about 1 point PRASM year-over-year in the first quarter. Conversely the third quarter and fourth quarter will experience a revenue tailwind of approximately $50 million and $25 million respectively. Second, we expect the average stage length of our routes to increase by approximately 1.5% in the quarter. This is mainly the result of restructuring our Pacific network. We now offer our customers a number of connections within Asia through our joint venture partner ANA allowing United to redeploy its aircraft to additional long haul routes from the US. For example, we eliminated certain shorter-haul flights out of Narita such as Hong Kong and Bangkok. In addition we ended our TAB flight between Melbourne and Sydney. In the same period we have added several long haul flights including Los Angeles to Melbourne and San Francisco to Taipei and Chengdu. While these decisions have proven to be margin accretive, they provide approximately 0.5 point of present headwind for the quarter. The third factor impacting our PRASM in the quarter is the effect of the strengthening dollar. While a strong dollar is good for our fuel purchasing, it reduces the revenue received from international ticket sales. The impact is somewhat muted because we spend a portion of our foreign currency to pay local expenses. In addition we have entered into currency hedge contracts to protect United from further weakness. Over the longer term, we believe that the strengthening dollar will generate additional demand in the US point of sale. For the first quarter, we estimate the foreign exchange impact to be approximately one point of PRASM headwind for the quarter. Finally while the domestic entity performed very well in 2014, it showed some signs of softening towards the end of the fourth quarter. We expect this to continue in the first quarter of 2015 with domestic unit revenues expected to be flat to up 2%. These unit revenue headwinds are partially offset by 1.5 point tailwind in the first quarter as we don't anticipate the same bubble of weather related disruption to our operation that we experienced in the first quarter of 2014. Turning to capacity. In the first quarter, we expect our consolidated capacity to be between flat and up 1% with domestic to be flat to down 1%. We still expect full year 2015 capacity to increase between 1.5% and 2.5%. With domestic capacity up 0.5% to 1.5%. The major driver of growth is the rollout of slimline seats. We currently have installed these seats on more than 300 aircrafts and installation will be 85% complete by the end of 2015. The remaining capacity growth will largely come from increasing our fleet utilization as our operation improves and the completion of aircraft modification of programs allows us to return aircraft to regular service. The impact of high utilization will represent nearly 14 additional aircraft becoming part of our fleet without spending any additional capital. In conclusion, I am pleased with the continuing progress of our revenue initiatives. Through the execution of our revenue plan, we are optimizing our network, our schedule, our revenue management practices and our express operation which we expect will lead to meaningful revenue growth in the upcoming quarters. With that, I'll turn the call over to Greg.
