Qatar Airways has been in talks over a stake in Italian carrier Meridiana and is planning to set up a domestic airline in India.
Al Baker also said the CSeries jet by Bombardier could fit for the domestic Indian carrier.
"Instead of ATRs or Q400s, I could use the CSeries on short-runway destinations in India," he said.
He added Qatar Airways was not interested in larger variants of the 737 MAX because it was ordering A321neo jets.
The carrier has been in talks with Airbus to change an order for A320neos for the larger A321neo variant after problems with the engines made by Pratt & Whitney.
Al Baker said he was close to finalising negotiations with Airbus to switch to the rival Leap engine made by CFM, a joint venture of General Electric and Safran.
