Why is that shouldn’t we be able to check in on line? Does this have something g to do with737 max issue? There is some possibility that the airline has had to switch aircraft. Was your friend was originally scheduled out of a 737 max8 or 737-800? If it now shows a 737-700 the problem may be not enough seats for everyone that bought tickets as the earlier planes seat 175 while the later one only seats 143, Your friend might try a twitter or e-mail question, but things are pretty jammed up due to cancellations. There are reports of long waits for return calls. That might be better than having your friend go to the airport and be told there is no seat available.
