Qatar Airways is operating a double daily Dreamliner service between its Doha hub and Delhi until June.
The Gulf airline started deploying a Boeing 787 to the Indian city on a daily basis last September (see news, August 20).
That ran alongside a second daily service that has been operated by an A330-200 and A330-300, depending on the day.
Now, from March 31 until June 1, Qatar Airways will temporarily replace that aircraft with a second B787, reports airlineroute.net.
Outbound flights QR564 and QR562 depart Doha at 0115 and arrive in Delhi at 0740 and 0300 the next day respectively.
Return services QR563 and QR565 take-off from Delhi at 0445 and 0920 and land in Doha at 0625 and 1100 respectively.
