A lot of the Thomas Cook repatriation flights have been operating via Las Palmas in both directions due to quite a few of their aircraft not having the range.
Obviously the long haul fleet is committed to its programmes and I believe that only 5 or 6 of the A321 fleet has the extra fuel pods installed for the longer routes and during the winter they already are scheduled to do the longer sectors to Hurgarda,Cape Verde and planned Banjul
