The earnings season kicks into high gear this week as investors seek more clues on how well corporate America is doing. Fifty-four S & P 500 companies are slated to report, including Tesla and Netflix. American and United Airlines are also on deck. Big banks JPMorgan Chase, Wells Fargo and Citigroup got the ball rolling last week, posting better-than-expected earnings. JPMorgan rose on the back of its results, but Wells and Citigroup ended Friday’s session lower. Roughly 30 S & P 500 names have reported thus far, with 80% of them exceeding analyst expectations, according to FactSet. Take a look at some of the key companies scheduled to post their latest numbers, and what to expect from them. Tuesday Bank of America is set to report earnings before the bell, followed by a call at 8:30 a.m. ET. Last quarter: BAC posted better-than-expected results thanks to higher rates . This quarter: Analysts polled by Refinitiv expect the banking giant’s profit rose double digits in the second quarter. What CNBC is watching: Bank of America earlier this month raised its dividend by 2 cents to 24 cents per share. Citi analyst Keith Horowitz noted that the company has one of the best core deposit franchises in the business, “but there is less flexibility on the asset side due to large HTM portfolio, so we believe NII trends will lag larger peers (JPM and WFC).” The analyst has a neutral rating on Bank of America shares. What history shows: Bank of America beats earnings expectations 78% of the time, according to Bespoke. In fact, the bank’s earnings have come in below estimates just twice since the second half of 2015. However, the stock averages a 0.8% decline on earnings days. Morgan Stanley is set to report earnings in the premarket, with a conference call slated for 9:30 a.m. ET. Last quarter: MS topped analyst expectations on strong bond revenue .

Last quarter: UAL posted a net loss but guided for a profit in the second quarter . This quarter: Analysts polled by Refinitiv expect the airline’s earnings to more than double. What CNBC airlines reporter Leslie Josephs is watching: “Despite strong demand and lower fuel prices, United had a rough end to the second quarter and start to the third after the Northeast was slammed day after day by thunderstorms, forcing hundreds of cancellations and thousands of delays with the airline’s Newark hub particularly hard-hit. Executives will detail the financial impact and expand on CEO Scott Kirby’s recent announcements that the company will have to trim its schedule at the congested Newark airport. Still, travel demand has remained strong, and international trips, one of United’s strengths, have been particularly robust. United will also give an update on outstanding labor contracts, including recent progress for a potential deal with pilots.” What history shows: United earnings beat expectations 69% of the time, Bespoke Investment Group data shows.

Thursday American Airlines is set to report earnings before the bell, followed by a call at 8:30 a.m. ET. Last quarter: AAL eked out a profit as the airline ramped up flying . This quarter: American’s earnings are expected to have doubled year over year, according to Refinitiv.

American says it will appeal the ruling, but JetBlue won’t, focusing instead on its plan to buy budget carrier Spirit. The airline will also likely update investors on labor negotiations with pilots and flight attendants, and its forecast for demand beyond the peak summer travel season.” What history shows: American Airlines beats earnings expectations 89% of the time, according to Bespoke. However, the stock averages a 0.2% decline on earnings day.
