Thanks, Brad, and hello, everybody. As Chris said, Air Group reported an adjusted net profit of $28.3 million compared to a $29.5 million profit last year. This result brings our trailing 12-month return on invested capital to 11.6% versus the 11.3% at the end of the first quarter last year. On an adjusted pretax basis, profit was down by $2 million from the 2011 first quarter, resulting in a slight decline in our pretax margin from 5.1% in 2011 to 4.5% this year.
The decline in earnings was primarily driven by the $62 million or 22% increase in economic fuel cost and a $21 million increase in adjusted nonfuel operating expenses. We were able to recapture nearly all of these cost increases with growth in operating revenues. Non-operating costs also fell by $7 million. Consolidated operating revenues were up $74 million or nearly 8% with the bulk of the increase coming from passenger revenue growth. Yields and load factors were up for both mainline and regional operations, which resulted in consolidated PRASM increasing by 4.7%.
With fuel on an economic basis, our all-in unit costs were up 5.8% from the 2011 first quarter, so our PRASM shortfall to maintain the same pretax margin was about 1 point. I know some of you have had some questions about our strong load factors, vis-à-vis our PRASM growth, which was not quite enough to cover the fuel and capacity-related cost increases. Brad provided some information from the 3 things that are driving load factor gains, culling flights with lower load factors, adding capacity in strong load factor markets and purposely managing load factors in January and February.
However, there are a few other things that are negatively impacting PRASM trends right now. First, we are growing capacity in long-haul markets such as Hawaii. Our average mainline stage length was up 2.9% over last year, the longer stage lengths put pressure on PRASM although there is certainly a CASM benefit as well.
Second, Mileage Plan redemption revenue, which is included in passenger revenue, was down $7.7 million or 15% this quarter. Although the number of awards redeemed is up slightly, the per mile rate used to recognize revenue is lower than last year. We expect this trend to continue through the third quarter.
And finally, ancillary revenues, specifically bag fees, are not keeping pace with the increasing capacity. Bag fee revenue, because of the Club 49 Alaska resident loyalty program and changing customer behavior was down about $2.8 million or 8% on a 4.2% increase in passengers. Although the bag fees are down, we believe there are still opportunities to increase ancillary revenues through things like hotels, cars, first-class upgrades and other products and services our customers value.
Most of you know that we report many ancillary revenues including bag fees and passenger revenue. Because our reporting convention is different than most others in the industry, starting next quarter we're going to report ancillary revenues in other revenue rather than in passenger revenue. We'll reclassify prior periods as well.
Turning now to costs. As I said a moment ago, economic fuel costs were up $62 million or 22%. Economic fuel price per gallon for the quarter was $3.41, up 19%. Our current guidance for the second quarter is $3.47. And to provide some context for all of 2011, our average economic fuel price per gallon was $3.18, which was the highest annual average ever. If fuel stays at current levels for the full year, we'll add $180 million to our fuel bill on top of the record costs in 2011. It's worth noting that the fuel comps are easier in the last 3 quarters of this year than they were in Q1.
We feel that we're well positioned to compete in this environment of higher fuel prices given our fleet, which is the most fuel efficient in the industry on a gallons-burned-per-RPM basis, our hedging program and our strong balance sheet. For the first quarter our hedges basically broke even. For the remainder of the year, we have 50% of our planned consumption hedged at $100 per barrel at an average premium cost of $10 per barrel. We also maintained short-term swaps on the refining margin and we are 50% hedged for the second quarter at $33 per barrel. We believe our hedging program offers more protection against rising fuel prices than any other airline in the industry.
The fuel efficiency of our fleet will get even better as we go forward. We're anxious to take delivery of our first 3 737-900ER aircrafts later this year. We now expect 22 of the 900ERs to come into our fleet between now and the end of 2014. With 181 seats, the 900ERs will be even more fuel efficient than our current airplanes on a per seat basis. Our nonfuel cost, excluding 2011 fleet transition costs increased by $21 million or 3.4% this quarter, meaning that consolidated CASM x fuel was basically flat. This was slightly better than our initial guidance of up 1%, although some planned spending has shifted a bit to the second and third quarters. For the second quarter, we again expect CASM to be flat and for the full year, however -- but for the full year, however, we still expect consolidated nonfuel unit costs to be down about 1.5%.
Moving to our balance sheet. We ended the quarter with just over $1.1 billion in cash and short-term investments, representing about 26% of trailing 12 months revenues. We generated $150 million of operating cash flow in the first quarter compared to $119 million last year. Capital spending was about $70 million during the quarter, so we, again, generated positive free cash flow. We took delivery of 2 737-800s during the quarter, and we'll get one more in May. All of the new Boeing Sky Interior which is getting rave reviews from our customers and our employees alike. And then as I said, our first 3 900ERs will be delivered in the fourth quarter. We recently exercised one and intend to exercise another 2 options for 737-900ERs that will be delivered in the fourth quarter of 2013. We're also finalizing a deal to sell and lease back under short-term leases 3 737-700s that will leave the fleet at roughly the same time the 3 new 900ERs arrive. In short, we're swapping out 3 smaller 700s for 3 larger 900ER airplanes.
The economics of up-gauging are attractive and the move reflects our bias toward larger aircraft. We also agreed to purchase 2 new Q400 aircraft from Bombardier to replace 2 of our older Q400s. The new aircraft will be delivered in the second quarter and the older 2 will go out of the fleet after the summer travel season. These 2 replacement aircraft will further improve Horizon's reliability.
With those changes, we now expect CapEx to be just over $500 million for the year. This figure does not include proceeds from the sale of the 3 700s. Even with a higher CapEx, we still expect to achieve our goal of generating free cash flow.
During the quarter, our board authorized a new $50 million stock repurchase program under, which we repurchased 203,000 shares for $7.1 million, bringing total first quarter repurchases to approximately $8.8 million. We also prepaid another $22 million worth of debt, along with approximately $37 million of normal debt prepayments, bringing our debt-to-cap ratio down to 60%.
We are now into what looks to be a third very good year in a row. Since the beginning of 2010, we have produced about $1.4 billion of operating cash flow, we've invested in the business by buying 9 737-800s and 2 Q400 aircraft, free and clear, that we've deployed to markets that are performing well. We've protected our shareholders from future shocks by reducing debt and lease obligations by $900 million and when combined with $345 million increase in equity, our debt-to-cap ratio has come down by 16 points. We've also returned capital to shareholders by repurchasing more than $130 million of our common stock. And although included in the operating cash flow numbers, we've contributed nearly $300 million to our pension plans when none was required and shared $165 million of incentive pay with our employees. We continue to believe that a balanced approach to capital allocation makes sense. Invest in the business, de-lever the balance sheet and provide a return to shareholders. Overall, it was a solid quarter, we continue to hit our ROIC goal, we produced our 12th consecutive quarterly profit that was near last year's record result. Despite the significant increase in fuel prices, we had record load factors and continued our excellent operational performance, we are all proud of these results.
At this time, I'll turn it back over to Brad to kick off the Q&A.
