Unless oil supply gets much worse I expect everyone to get to their destination, with so many scheduled fights being cancelled, it's bound to cause rescheduling.
All airlines will have fuel bought forward to cover most of their flights, the problem is the many oil producers and refineries are declaring "Force Majeure" - they cannot fulfill the contract because of gulf war. So oil has to be bought at market rate to fly
If the blockade continues for several/many months there will be shortages, some airlines, including Air France and Virgin have already applied fuel surcharges.
